Geometric and Topological Inference (Cambridge Texts in Applied Mathematics #57)
by Jean-Daniel Boissonnat Frédéric Chazal Mariette YvinecGeometric and topological inference deals with the retrieval of information about a geometric object using only a finite set of possibly noisy sample points. It has connections to manifold learning and provides the mathematical and algorithmic foundations of the rapidly evolving field of topological data analysis. Building on a rigorous treatment of simplicial complexes and distance functions, this self-contained book covers key aspects of the field, from data representation and combinatorial questions to manifold reconstruction and persistent homology. It can serve as a textbook for graduate students or researchers in mathematics, computer science and engineering interested in a geometric approach to data science.
Geometric and Topological Mesh Feature Extraction for 3D Shape Analysis
by Jean-Luc Mari Franck Hétroy-Wheeler Gérard SubsolThree-dimensional surface meshes are the most common discrete representation of the exterior of a virtual shape. Extracting relevant geometric or topological features from them can simplify the way objects are looked at, help with their recognition, and facilitate description and categorization according to specific criteria. This book adopts the point of view of discrete mathematics, the aim of which is to propose discrete counterparts to concepts mathematically defined in continuous terms. It explains how standard geometric and topological notions of surfaces can be calculated and computed on a 3D surface mesh, as well as their use for shape analysis. Several applications are also detailed, demonstrating that each of them requires specific adjustments to fit with generic approaches. The book is intended not only for students, researchers and engineers in computer science and shape analysis, but also numerical geologists, anthropologists, biologists and other scientists looking for practical solutions to their shape analysis, understanding or recognition problems.
Geometrical Formulation of Renormalization-Group Method as an Asymptotic Analysis: With Applications to Derivation of Causal Fluid Dynamics (Fundamental Theories of Physics #206)
by Teiji Kunihiro Yuta Kikuchi Kyosuke TsumuraThis book presents a comprehensive account of the renormalization-group (RG) method and its extension, the doublet scheme, in a geometrical point of view. It extract long timescale macroscopic/mesoscopic dynamics from microscopic equations in an intuitively understandable way rather than in a mathematically rigorous manner and introduces readers to a mathematically elementary, but useful and widely applicable technique for analyzing asymptotic solutions in mathematical models of nature. The book begins with the basic notion of the RG theory, including its connection with the separation of scales. Then it formulates the RG method as a construction method of envelopes of the naive perturbative solutions containing secular terms, and then demonstrates the formulation in various types of evolution equations. Lastly, it describes successful physical examples, such as stochastic and transport phenomena including second-order relativistic as well as nonrelativistic fluid dynamics with causality and transport phenomena in cold atoms, with extensive numerical expositions of transport coefficients and relaxation times. Requiring only an undergraduate-level understanding of physics and mathematics, the book clearly describes the notions and mathematical techniques with a wealth of examples. It is a unique and can be enlightening resource for readers who feel mystified by renormalization theory in quantum field theory.
Geometrical Kaleidoscope (Dover Books on Mathematics)
by Boris PritskerA high school course in geometry and some curiosity and enthusiasm for the subject are the only prerequisites for tackling this original exploration into the field, long a favorite for readers whose interest in math is not only practical and educational, but also recreational. The book centers on geometric thinking—what it means, how to develop it, and how to recognize it. Readers will discover fascinating insights into many aspects of geometry and geometrical properties and theorems, including such classic examples as Archimedes' law of the lever, Euler's line and circle properties, Fagnano's problem, and Napoleon's theorem.The volume is divided into sections on individual topics such as "Medians of a Triangle," and "Area of a Quadrilateral." Chapters typically begin with some interesting geometrical history, some relevant theorems, and some worked examples of problems followed by problems for readers to figure out for themselves (solutions are provided at the end of the book). The result is a many-faceted exploration, rather like a kaleidoscope, focusing on the mysteries and the pleasures of geometry.

Geometrical Objects
by Anthony GerbinoThis volume explores the mathematical character of architectural practice in diverse pre- and early modern contexts It takes an explicitly interdisciplinary approach, which unites scholarship in early modern architecture with recent work in the history of science, in particular, on the role of practice in the "scientific revolution" As a contribution to architectural history, the volume contextualizes design and construction in terms of contemporary mathematical knowledge, attendant forms of mathematical practice, and relevant social distinctions between the mathematical professions As a contribution to the history of science, the volume presents a series of micro-historical studies that highlight issues of process, materiality, and knowledge production in specific, situated, practical contexts Our approach sees the designer's studio, the stone-yard, the drawing floor, and construction site not merely as places where the architectural object takes shape, but where mathematical knowledge itself is deployed, exchanged, and amplified among various participants in the building process.
Geometrical Themes Inspired by the N-body Problem (Lecture Notes in Mathematics #2204)
by Luis Hernández-Lamoneda Haydeé Herrera Rafael HerreraPresenting a selection of recent developments in geometrical problems inspired by the N-body problem, these lecture notes offer a variety of approaches to study them, ranging from variational to dynamical, while developing new insights, making geometrical and topological detours, and providing historical references. A. Guillot’s notes aim to describe differential equations in the complex domain, motivated by the evolution of N particles moving on the plane subject to the influence of a magnetic field. Guillot studies such differential equations using different geometric structures on complex curves (in the sense of W. Thurston) in order to find isochronicity conditions. R. Montgomery’s notes deal with a version of the planar Newtonian three-body equation. Namely, he investigates the problem of whether every free homotopy class is realized by a periodic geodesic. The solution involves geometry, dynamical systems, and the McGehee blow-up. A novelty of the approach is the use of energy-balance in order to motivate the McGehee transformation. A. Pedroza’s notes provide a brief introduction to Lagrangian Floer homology and its relation to the solution of the Arnol’d conjecture on the minimal number of non-degenerate fixed points of a Hamiltonian diffeomorphism.
Geometrical Vectors (Chicago Lectures In Physics Ser.)
by Gabriel WeinreichEvery advanced undergraduate and graduate student of physics must master the concepts of vectors and vector analysis. Yet most books cover this topic by merely repeating the introductory-level treatment based on a limited algebraic or analytic view of the subject. <P><P> Geometrical Vectors introduces a more sophisticated approach, which not only brings together many loose ends of the traditional treatment, but also leads directly into the practical use of vectors in general curvilinear coordinates by carefully separating those relationships which are topologically invariant from those which are not. Based on the essentially geometric nature of the subject, this approach builds consistently on students' prior knowledge and geometrical intuition. <P><P> Written in an informal and personal style, Geometrical Vectors provides a handy guide for any student of vector analysis. Clear, carefully constructed line drawings illustrate key points in the text, and problem sets as well as physical examples are provided.

Geometrical methods of mathematical physics
by Bernard F. SchutzIn recent years the methods of modern differential geometry have become of considerable importance in theoretical physics and have found application in relativity and cosmology, high-energy physics and field theory, thermodynamics, fluid dynamics and mechanics. This textbook provides an introduction to these methods - in particular Lie derivatives, Lie groups and differential forms - and covers their extensive applications to theoretical physics. The reader is assumed to have some familiarity with advanced calculus, linear algebra and a little elementary operator theory. The advanced physics undergraduate should therefore find the presentation quite accessible. This account will prove valuable for those with backgrounds in physics and applied mathematics who desire an introduction to the subject. Having studied the book, the reader will be able to comprehend research papers that use this mathematics and follow more advanced pure-mathematical expositions.
Geometrically Constructed Markov Chain Monte Carlo Study of Quantum Spin-phonon Complex Systems
by Hidemaro SuwaIn this thesis, novel Monte Carlo methods for precisely calculating the critical phenomena of the effectively frustrated quantum spin system are developed and applied to the critical phenomena of the spin-Peierls systems. Three significant methods are introduced for the first time: a new optimization algorithm of the Markov chain transition kernel based on the geometric weight-allocation approach, the extension of the worm (directed-loop) algorithm to nonconserved particles, and the combination with the level spectroscopy. Utilizing these methods, the phase diagram of the one-dimensional XXZ spin-Peierls system is elucidated. Furthermore, the multi-chain and two-dimensional spin-Peierls systems with interchain lattice interaction are investigated. The unbiased simulation shows that the interesting quantum phase transition between the 1D-like liquid phase and the macroscopically-degenerated dimer phase occurs on the fully-frustrated parameter line that separates the doubly-degenerated dimer phases in the two-dimensional phase diagram. The spin-phonon interaction in the spin-Peierls system introduces the spin frustration, which usually hinders the quantum Monte Carlo analysis, owing to the notorious negative sign problem. In this thesis, the author has succeeded in precisely calculating the critical phenomena of the effectively frustrated quantum spin system by means of the quantum Monte Carlo method without the negative sign.

Geometrie der Allgemeinen Relativitätstheorie: Eine Einführung aus differentialgeometrischer Perspektive (BestMasters)
by Lukas ScharfeZu Recht wird Albert Einsteins Entdeckung der Allgemeinen Relativitätstheorie bewundert, denn ihre Erkenntnisse haben unseren Blick auf das Universum grundlegend verändert. Aus mathematischer Perspektive basiert die Theorie auf zentralen Aussagen der Riemann’schen Geometrie. Dieses Buch liefert eine didaktisch aufbereitete und interdisziplinäre Einführung in die Geometrie der Allgemeinen Relativitätstheorie. Ausgehend von Einsteins typischen Überlegungen und Gedankenexperimenten werden die Prinzipien der Relativitätstheorie erarbeitet und mit den zugrundeliegenden mathematischen Konzepten der Differentialgeometrie verknüpft.Der Autor bietet durch die Verbindung beider Fachdisziplinen sowohl für Studierende der Physik als auch der Mathematik die Möglichkeit, in eine der faszinierendsten Theorien der Physik einzutauchen.
Geometrie der Raumzeit: Eine mathematische Einführung in die Relativitätstheorie
by Rainer OloffDie Relativitätstheorie ist in ihren Kernaussagen nicht mehr umstritten, gilt aber noch immer als kompliziert und nur schwer verstehbar. Das liegt unter anderem an dem aufwendigen mathematischen Apparat, der schon zur Formulierung ihrer Ergebnisse und erst recht zum Nachvollziehen der Argumentation notwendig ist. In diesem Lehrbuch werden die mathematischen Grundlagen der Relativitätstheorie systematisch entwickelt, das ist die Differentialgeometrie auf Mannigfaltigkeiten einschließlich Differentiation und Integration. Die Spezielle Relativitätstheorie wird als Tensorrechnung auf den Tangentialräumen dargestellt. Die zentrale Aussage der Allgemeinen Relativitätstheorie ist die Einstein'sche Feldgleichung, die die Krümmung zur Materie in Beziehung setzt. Ausführlich werden die relativistischen Effekte im Sonnensystem einschließlich der Schwarzen Löcher behandelt. Dieser Text richtet sich an Studierende der Physik und der Mathematik und setzt nur Grundkenntnisse aus der klassischen Differential- und Integralrechnung und der Linearen Algebra voraus. Für die neue Auflage wurde das Buch durchgesehen und alle bekannt gewordenen Fehler korrigiert.
Geometrie und GPS: Mathematische, physikalische und technische Grundlagen der Satellitenortung verständlich erklärt (Mathematik Primarstufe und Sekundarstufe I + II)
by Helmut AlbrechtAls am 4. Oktober 1957 der erste Satellit in eine Erdumlaufbahn gebracht wurde, dachte noch niemand an eine Positionsbestimmung mit Hilfe von Satelliten, und doch war „Sputnik I“ der Wegbereiter der heutigen Satellitennavigationssysteme. Ursprünglich als rein militärische Anwendung konzipiert, wird die Satellitenortung heute überwiegend zivil genutzt, und neben dem amerikanischen GPS gibt es heute mit Galileo, Glonass und Beidou weitere gleichartige Systeme.Das grundsätzliche Funktionsprinzip der Satellitenortung kann man überall nachlesen – aber damit beginnen erst die wirklich interessanten Fragen:Woher kennt man den genauen Standort der Satelliten?Wie kann man exakte Entfernungen zu Satelliten bestimmen, die über 20.000 km entfernt sind?Warum nennt man diese Entfernungen „Pseudoentfernungen“?Wieso werden an Bord der Satelliten Atomuhren mitgeführt?Was ermöglicht einem Empfänger, die empfangenen Daten zu unterscheiden, wo doch alle Satelliten auf ein und derselben Frequenz senden?Wie kann man aus den Entfernungen und den Satellitenorten die Empfängerposition berechnen?Warum taugt das Kugelmodell der Erde nicht für eine exakte Positionsbestimmung?Was ist, wenn Daten von mehr als den benötigten vier Satelliten zur Verfügung stehen?Warum sind sogar relativistische Effekte zu berücksichtigen?Dieses Buch gibt nicht nur verständliche und erschöpfende Antworten auf diese und viele weitere Fragen, sondern ermöglicht es interessierten Leserinnen und Lesern, die notwendigen Berechnungen von der Datengewinnung bis hin zur verblüffend exakten Positionsbestimmung mit Hilfe des Computer-Algebra-Systems Maxima Schritt für Schritt selbst nachzuvollziehen. Nicht zuletzt liefert es eine überzeugende Antwort auf die allgegenwärtige Frage von Schülern und Studierenden, wozu man denn all die Geometrie, Analysis und lineare Algebra überhaupt benötigt.Schließlich greift das Buch über die Mathematik hinaus Themen aus der Physik, der Astronomie, der Nachrichtentechnik und der Datenverarbeitung auf und motiviert so zu einer spannenden Anwendung innerhalb des MINT-Bereichs.
Geometrie – Anschauung und Begriffe: Vorstellen, Verstehen, Weiterdenken. Eine Einführung für Studierende.
by Jost-Hinrich EschenburgDieses Buch behandelt die Geometrie des Anschauungsraums in allen ihren Aspekten. Wie in jedem Teilgebiet der Mathematik geht es darum, das Verborgene auf das Offensichtliche zurückzuführen; die Besonderheit der Geometrie ist, dass das Offensichtliche manchmal im wörtlichen Sinne vor Augen liegt.Ausgehend von der Anschauung werden räumliche Konzepte in das bereits vorhandene mathematische Gerüst der Linearen Algebra und der Analysis eingebettet. Der Weg von der Anschauung zur mathematisch exakten Sprache ist selbst Lerninhalt dieses Buches. Damit soll eine oft beklagte Verstehenslücke geschlossen werden, die sich zwischen der anschaulichen Vorschul- und Schul- Geometrie und den abstrakten Begriffen der Linearen Algebra und Analysis auftut. Zugleich werden damit anschaulich-geometrische Argumentationsweisen gerechtfertigt, weil ihre Einbettung in die strenge mathematische Sprache geklärt wurde.Die Begriffe der Geometrie sind von ganz unterschiedlicher Natur; sie bezeichnen sozusagen verschiedene Schichten geometrischen Denkens: Manche Argumente verwenden nur Begriffe wie Punkt, Gerade und Inzidenz, andere benötigen Winkel und Abstände, wieder andere Symmetrie-Überlegungen. Jedes dieser Begriffsfelder bestimmt ein eigenes Teilgebiet der Geometrie und ein eigenes Kapitel dieses Buches, mit Ausnahme des letztgenannte Begriffsfelds "Symmetrie", das alle anderen durchzieht: - Inzidenz: Projektive Geometrie - Parallelität: Affine Geometrie - Winkel: Konforme Geometrie - Abstand: Metrische Geometrie - Krümmung: Differentialgeometrie - Winkel als Abstandsmaß: Sphärische und Hyperbolische Geometrie - Symmetrie: Abbildungsgeometrie.Die im Anschauungsraum erworbene mathematische Erfahrung lässt sich ohne Mühe mit Hilfe des Vektorraum-Begriffs auf sehr viel abstraktere Situationen übertragen. Die Verallgemeinerungen über die Anschauung hinaus weisen in zwei Richtungen: Erweiterung des Zahlbegriffs und Überschreiten der drei anschaulichen Dimensionen.
Geometries And Transformations
by Norman W. JohnsonEuclidean and other geometries are distinguished by the transformations that preserve their essential properties.<P><P> Using linear algebra and transformation groups, this book provides a readable exposition of how these classical geometries are both differentiated and connected. Following Cayley and Klein, the book builds on projective and inversive geometry to construct 'linear' and 'circular' geometries, including classical real metric spaces like Euclidean, hyperbolic, elliptic, and spherical, as well as their unitary counterparts. The first part of the book deals with the foundations and general properties of the various kinds of geometries. The latter part studies discrete-geometric structures and their symmetries in various spaces. Written for graduate students, the book includes numerous exercises and covers both classical results and new research in the field. An understanding of analytic geometry, linear algebra, and elementary group theory is assumed.<P> Provides a unified framework for describing Euclidean and non-Euclidean geometries.<P> Demonstrates the interconnectedness of different geometries using linear algebra.<P> Includes both classical results and contemporary research, as well as numerous exercises.
Geometries of Anamorphic Illusions: Landscape, Architecture, Contemporary Art and Design (The Urban Book Series)
by Alessandra PaglianoThis book intends to focus exclusively on anamorphic experiments in contemporary art and design, leaving an in-depth historical examination of its Baroque season to other studies. Themes, languages and fields of application of anamorphosis in contemporary culture are critically analyzed to make the reader aware of the communicative potentiality of this kind of geometrical technique. The book also has the aim to teach the reader the most appropriate geometric techniques for each of them, in order to achieve the designed illusion. Each typology of anamorphosis is accompanied in this book by contemporary installations, a geometrical explanation by means of 3D models and didactic experiments carried on in collaboration with the students of the Department of Architecture in Naples.
