Direct and Inverse Scattering for the Matrix Schrödinger Equation (Applied Mathematical Sciences #203)
by Tuncay Aktosun Ricardo WederAuthored by two experts in the field who have been long-time collaborators, this monograph treats the scattering and inverse scattering problems for the matrix Schrödinger equation on the half line with the general selfadjoint boundary condition. The existence, uniqueness, construction, and characterization aspects are treated with mathematical rigor, and physical insight is provided to make the material accessible to mathematicians, physicists, engineers, and applied scientists with an interest in scattering and inverse scattering. The material presented is expected to be useful to beginners as well as experts in the field. The subject matter covered is expected to be interesting to a wide range of researchers including those working in quantum graphs and scattering on graphs. The theory presented is illustrated with various explicit examples to improve the understanding of scattering and inverse scattering problems. The monograph introduces a specific class of input data sets consisting of a potential and a boundary condition and a specific class of scattering data sets consisting of a scattering matrix and bound-state information. The important problem of the characterization is solved by establishing a one-to-one correspondence between the two aforementioned classes. The characterization result is formulated in various equivalent forms, providing insight and allowing a comparison of different techniques used to solve the inverse scattering problem. The past literature treated the type of boundary condition as a part of the scattering data used as input to recover the potential. This monograph provides a proper formulation of the inverse scattering problem where the type of boundary condition is no longer a part of the scattering data set, but rather both the potential and the type of boundary condition are recovered from the scattering data set.
Fundamentals of Real and Complex Analysis (Springer Undergraduate Mathematics Series)
by Asuman Güven AksoyThe primary aim of this text is to help transition undergraduates to study graduate level mathematics. It unites real and complex analysis after developing the basic techniques and aims at a larger readership than that of similar textbooks that have been published, as fewer mathematical requisites are required. The idea is to present analysis as a whole and emphasize the strong connections between various branches of the field. Ample examples and exercises reinforce concepts, and a helpful bibliography guides those wishing to delve deeper into particular topics. Graduate students who are studying for their qualifying exams in analysis will find use in this text, as well as those looking to advance their mathematical studies or who are moving on to explore another quantitative science.Chapter 1 contains many tools for higher mathematics; its content is easily accessible, though not elementary. Chapter 2 focuses on topics in real analysis such as p-adic completion, Banach Contraction Mapping Theorem and its applications, Fourier series, Lebesgue measure and integration. One of this chapter’s unique features is its treatment of functional equations. Chapter 3 covers the essential topics in complex analysis: it begins with a geometric introduction to the complex plane, then covers holomorphic functions, complex power series, conformal mappings, and the Riemann mapping theorem. In conjunction with the Bieberbach conjecture, the power and applications of Cauchy’s theorem through the integral formula and residue theorem are presented.
Enlargement of Filtration with Finance in View
by Anna Aksamit Monique JeanblancIn addition to presenting the basic theory of enlargement of filtrations, this book also includes new material and applications to finance. The main results are applied to give conditions which ensure that new information does not provide arbitrage opportunities, and in those cases where the arbitrages exist, they are explicitly constructed. Numerous examples are provided together with a list of recent papers on the subject. The presentation has been kept as simple as possible. In particular, sophisticated new results are given without proofs. Addressing the question of how to model and study new information flows, the theory of enlargement of filtrations is used in credit risk modeling, insider trading and in the study of asymmetric information. This book fills a gap in the literature and will be useful to students and researchers interested in the role of information, both in financial mathematics and in econometric science.

Substitution and Tiling Dynamics: CIRM Jean-Morlet Chair, Fall 2017 (Lecture Notes in Mathematics #2273)
by Shigeki Akiyama Pierre ArnouxThis book presents a panorama of recent developments in the theory of tilings and related dynamical systems. It contains an expanded version of courses given in 2017 at the research school associated with the Jean-Morlet chair program.Tilings have been designed, used and studied for centuries in various contexts. This field grew significantly after the discovery of aperiodic self-similar tilings in the 60s, linked to the proof of the undecidability of the Domino problem, and was driven futher by Dan Shechtman's discovery of quasicrystals in 1984. Tiling problems establish a bridge between the mutually influential fields of geometry, dynamical systems, aperiodic order, computer science, number theory, algebra and logic. The main properties of tiling dynamical systems are covered, with expositions on recent results in self-similarity (and its generalizations, fusions rules and S-adic systems), algebraic developments connected to physics, games and undecidability questions, and the spectrum of substitution tilings.

Algebraisches Denken im Arithmetikunterricht der Grundschule: Muster entdecken – Strukturen verstehen (Mathematik Primarstufe und Sekundarstufe I + II)
by Kathrin Akinwunmi Anna Susanne SteinwegDieses Buch thematisiert algebraisches Denken in der Grundschule als wesentlichen Kern der übergreifenden Leitidee „Muster, Strukturen und funktionaler Zusammenhang“ in den aktuellen KMK-Bildungsstandards.Für algebraische Lehr-Lernprozesse ist eine Unterscheidung zwischen sichtbaren Mustern und allgemeinen Strukturen wesentlich; eine solche wird hier vorgelegt und an vielen Beispielen konkretisiert: Muster machen aufmerksam und lassen neugierig werden. Die Suche nach Begründungen des Musters erwartet, die Tür zu dahinterliegenden Strukturen zu öffnen. Strukturen, d. h. die mathematischen Eigenschaften und Relationen, können so als ursächlich für die Regelmäßigkeit des Musters erkannt werden.Für die unterrichtliche Förderung und gezielte Unterstützung der algebraischen Denkentwicklung werden in diesem Buch einerseits Grundideen algebraischen Denkens für den Arithmetikunterricht ausgearbeitet und andererseits Prinzipien für Unterricht zu algebraischen Grundideen und ihr Zusammenspiel mit prozessbezogenen, allgemeinen Kompetenzen erläutert. Den vier algebraischen Grundideen folgend werden vielfältige, didaktisch aufbereitete Anregungen zur praktischen Umsetzung sowie jeweils entsprechendes Hintergrundwissen angeboten.Das Buch richtet sich an Lehramtsstudierende, an angehende und bereits praktizierende Lehrkräfte sowie an Personen, die in der Lehrerinnen- und Lehrerbildung tätig sind.
Zur Entwicklung von Variablenkonzepten beim Verallgemeinern mathematischer Muster
by Kathrin AkinwunmiDas Verallgemeinern mathematischer Muster ist eine grundlegende Tätigkeit des Mathematikunterrichts und zugleich ein zentraler Zugang zur Algebra. Dies nutzt Kathrin Akinwunmi, um sich mit der propädeutischen Entwicklung von Variablenkonzepten in der Grundschule zu beschäftigen. Sie geht der Frage nach, wie GrundschülerInnen Muster verallgemeinern und wie sich dabei Variablenkonzepte entwickeln. In einer Interviewstudie mit 30 ViertklässlerInnen untersucht die Autorin die Verallgemeinerungsprozesse der Lernenden aus epistemologischer Perspektive. In der Datenanalyse rekonstruiert sie Begriffsbildungsprozesse zu Variablenkonzepten und arbeitet sprachliche Mittel heraus, welche die Lernenden bei Verallgemeinerungen mathematischer Muster nutzen.

Bifurcation in Autonomous and Nonautonomous Differential Equations with Discontinuities (Nonlinear Physical Science)
by Marat Akhmet Ardak KashkynbayevThis book is devoted to bifurcation theory for autonomous and nonautonomous differential equations with discontinuities of different types. That is, those with jumps present either in the right-hand-side or in trajectories or in the arguments of solutions of equations. The results obtained in this book can be applied to various fields such as neural networks, brain dynamics, mechanical systems, weather phenomena, population dynamics, etc. Without any doubt, bifurcation theory should be further developed to different types of differential equations. In this sense, the present book will be a leading one in this field. The reader will benefit from the recent results of the theory and will learn in the very concrete way how to apply this theory to differential equations with various types of discontinuity. Moreover, the reader will learn new ways to analyze nonautonomous bifurcation scenarios in these equations. The book will be of a big interest both for beginners and experts in the field. For the former group of specialists, that is, undergraduate and graduate students, the book will be useful since it provides a strong impression that bifurcation theory can be developed not only for discrete and continuous systems, but those which combine these systems in very different ways. The latter group of specialists will find in this book several powerful instruments developed for the theory of discontinuous dynamical systems with variable moments of impacts, differential equations with piecewise constant arguments of generalized type and Filippov systems. A significant benefit of the present book is expected to be for those who consider bifurcations in systems with impulses since they are presumably nonautonomous systems.
Dynamics with Chaos and Fractals (Nonlinear Systems and Complexity #29)
by Marat Akhmet Mehmet Onur Fen Ejaily Milad AlejailyThe book is concerned with the concepts of chaos and fractals, which are within the scopes of dynamical systems, geometry, measure theory, topology, and numerical analysis during the last several decades. It is revealed that a special kind of Poisson stable point, which we call an unpredictable point, gives rise to the existence of chaos in the quasi-minimal set. This is the first time in the literature that the description of chaos is initiated from a single motion. Chaos is now placed on the line of oscillations, and therefore, it is a subject of study in the framework of the theories of dynamical systems and differential equations, as in this book. The techniques introduced in the book make it possible to develop continuous and discrete dynamics which admit fractals as points of trajectories as well as orbits themselves. To provide strong arguments for the genericity of chaos in the real and abstract universe, the concept of abstract similarity is suggested.

Replication of Chaos in Neural Networks, Economics and Physics
by Marat Akhmet Mehmet Onur FenThis book presents detailed descriptions of chaos for continuous-time systems. It is the first-ever book to consider chaos as an input for differential and hybrid equations. Chaotic sets and chaotic functions are used as inputs for systems with attractors: equilibrium points, cycles and tori. The findings strongly suggest that chaos theory can proceed from the theory of differential equations to a higher level than previously thought. The approach selected is conducive to the in-depth analysis of different types of chaos. The appearance of deterministic chaos in neural networks, economics and mechanical systems is discussed theoretically and supported by simulations. As such, the book offers a valuable resource for mathematicians, physicists, engineers and economists studying nonlinear chaotic dynamics.
Almost Periodicity, Chaos, and Asymptotic Equivalence (Nonlinear Systems and Complexity #27)
by Marat AkhmetThe central subject of this book is Almost Periodic Oscillations, the most common oscillations in applications and the most intricate for mathematical analysis. Prof. Akhmet's lucid and rigorous examination proves these oscillations are a "regular" component of chaotic attractors. The book focuses on almost periodic functions, first of all, as Stable (asymptotically) solutions of differential equations of different types, presumably discontinuous; and, secondly, as non-isolated oscillations in chaotic sets. Finally, the author proves the existence of Almost Periodic Oscillations (asymptotic and bi-asymptotic) by asymptotic equivalence between systems. The book brings readers' attention to contemporary methods for considering oscillations as well as to methods with strong potential for study of chaos in the future. Providing three powerful instruments for mathematical research of oscillations where dynamics are observable and applied, the book is ideal for engineers as well as specialists in electronics, computer sciences, robotics, neural networks, artificial networks, and biology.Distinctively combines results and methods of the theory of differential equations with thorough investigation of chaotic dynamics with almost periodic ingredients;Provides all necessary mathematical basics in their most developed form, negating the need for any additional sources for readers to start work in the area;Presents a unique method of investigation of discontinuous almost periodic solutions in its unified form, employed to differential equations with different types of discontinuity;Develops the equivalence method to its ultimate effective state such that most important theoretical problems and practical applications can be analyzed by the method.
Principles of Discontinuous Dynamical Systems
by Marat AkhmetDiscontinuous dynamical systems have played an important role in both theory and applications during the last several decades. This is still an area of active research and techniques to make the applications more effective are an ongoing topic of interest. Principles of Discontinuous Dynamical Systems is devoted to the theory of differential equations with variable moments of impulses. It introduces a new strategy of implementing an equivalence to systems whose solutions have prescribed moments of impulses and utilizing special topologies in spaces of piecewise continuous functions. The achievements obtained on the basis of this approach are described in this book. The text progresses systematically, by covering preliminaries in the first four chapters. This is followed by more complex material and special topics such as Hopf bifurcation, Devaney's chaos, and the shadowing property are discussed in the last two chapters. This book is suitable for researchers and graduate students in mathematics and also in diverse areas such as biology, computer science, and engineering who deal with real world problems.
Selected Special Functions for Fundamental Physics (SpringerBriefs in Physics)
by Valeriya Akhmedova Emil T. AkhmedovThis book presents calculation methods that are used in both mathematical and theoretical physics. These methods will allow readers to work with selected special functions and more generally with differential equations, which are the most frequently used in quantum mechanics, theory of relativity and quantum field theory. The authors explain various approximation methods used to solve differential equations and to estimate integrals. They also address the basics of the relations between differential equations, special functions and representation theory of some of the simplest algebras on the one hand, and fundamental physics on the other. Based on a seminar for graduate physics students, the book offers a compact and quick way to learn about special functions. To gain the most from it, readers should be familiar with the basics of calculus, linear algebra, and complex analysis, as well as the basic methods used to solve differential equations and calculate integrals.
