Hangzhou Lectures on Eigenfunctions of the Laplacian (Annals of Mathematics Studies #188)
by Christopher D. SoggeBased on lectures given at Zhejiang University in Hangzhou, China, and Johns Hopkins University, this book introduces eigenfunctions on Riemannian manifolds. Christopher Sogge gives a proof of the sharp Weyl formula for the distribution of eigenvalues of Laplace-Beltrami operators, as well as an improved version of the Weyl formula, the Duistermaat-Guillemin theorem under natural assumptions on the geodesic flow. Sogge shows that there is quantum ergodicity of eigenfunctions if the geodesic flow is ergodic.Sogge begins with a treatment of the Hadamard parametrix before proving the first main result, the sharp Weyl formula. He avoids the use of Tauberian estimates and instead relies on sup-norm estimates for eigenfunctions. The author also gives a rapid introduction to the stationary phase and the basics of the theory of pseudodifferential operators and microlocal analysis. These are used to prove the Duistermaat-Guillemin theorem. Turning to the related topic of quantum ergodicity, Sogge demonstrates that if the long-term geodesic flow is uniformly distributed, most eigenfunctions exhibit a similar behavior, in the sense that their mass becomes equidistributed as their frequencies go to infinity.
Hank Greenberg in 1938: Hatred and Home Runs in the Shadow of War
by Ron Kaplan"Hammerin’” Hank Greenberg was coming off a stellar season where he’d hit 40 home runs and 184 RBIs, becoming only the thirteenth player to ever hit 40 or more homers (and one of only four players to have 40 or more home runs and 175 or more RBIs in a season). Even with his success at the plate, neither Greenberg nor the rest of the world could have expected what was about to happen in 1938. From his first day in the big leagues, the New York-born Greenberg had dealt with persecution for being Jewish. From teammate Jo-Jo White asking where his horns were to the verbal abuse from bigoted fans and the media, the 6-foot-3 slugger always did his best to shut the noise out and concentrate on baseball. But in 1938, that would be more difficult then he could have ever imagined.While Greenberg was battling at the plate, his people overseas were dealing with a completely different battle. Adolf Hitler, who had been chancellor of Germany since 1933, had taken direct control of the country’s military in February of ’38. He then began his methodic takeover of all neighboring countries, spreading Nazism and the early stages of World War II and the Holocaust.Hank Greenberg in 1938 chronicles the events of 1938, both on the baseball diamond and the streets of Europe. As Greenberg’s bat had him on course for Babe Ruth’s home run record, Hitler’s "Final Solution” was beginning to take shape. Jews across the US, worried about the issues overseas, looked to Greenberg as a symbol of hope. Though normally hesitant to speak about the anti-Semitism he dealt with, the slugger still knew the role he was playing for so many of his people, saying "I came to feel that if I, as a Jew, hit a home run, I was hitting one against Hitler.”
Happiness and Wellbeing in Singapore: Beyond Economic Prosperity (Routledge Focus on Business and Management)
by Siok Kuan Tambyah Soo Jiuan Tan Yuen Wei LunTo present a multifaceted and holistic perspective of what makes Singaporeans happy, Tambyah, Tan and Yuen discuss the findings and insights from the 2022 Quality of Life Survey, which examines the perceptions and views of 1,905 Singapore citizens. This is the latest survey in a series of studies on the wellbeing of Singaporeans. While the impact of the COVID- 19 pandemic on wellbeing is a timely discussion, the findings are also compared with previous surveys conducted in 2011 and 2016 to provide a longitudinal perspective of how Singaporeans’ wellbeing has evolved over the years. Key aspects of this topic include life satisfaction and satisfaction with specific life domains, aspects of affective wellbeing (e.g., happiness, enjoyment and achievement), economic wellbeing, psychological flourishing, personal values, value orientations and views on socio- political issues. Pertinent differences due to demographics such as gender, marital status, age, education and household income are also highlighted. The book also features four archetypes and clusters of Singaporeans, which are representative of the unique demographics, values and wellbeing outcomes examined. The findings and insights will be useful to academics, policy makers, practitioners, students and the general public who are interested in understanding the life satisfaction and wellbeing of Singaporeans.

Haptic Interaction with Deformable Objects
by Guido BöttcherThe focus from most Virtual Reality (VR) systems lies mainly on the visual immersion of the user. But the emphasis only on the visual perception is insufficient for some applications as the user is limited in his interactions within the VR. Therefore the textbook presents the principles and theoretical background to develop a VR system that is able to create a link between physical simulations and haptic rendering which requires update rates of 1\,kHz for the force feedback. Special attention is given to the modeling and computation of contact forces in a two-finger grasp of textiles. Addressing further the perception of small scale surface properties like roughness, novel algorithms are presented that are not only able to consider the highly dynamic behaviour of textiles but also capable of computing the small forces needed for the tactile rendering at the contact point. Final analysis of the entire VR system is being made showing the problems and the solutions found in the work
The Harary Index of a Graph
by Kexiang Xu Kinkar Ch. Das Nenad TrinajstićThis is the first book to focus on the topological index, the Harary index, of a graph, including its mathematical properties, chemical applications and some related and attractive open problems. This book is dedicated to Professor Frank Harary (1921--2005), the grandmaster of graph theory and its applications. It has be written by experts in the field of graph theory and its applications. For a connected graph G, as an important distance-based topological index, the Harary index H(G) is defined as the sum of the reciprocals of the distance between any two unordered vertices of the graph G. In this book, the authors report on the newest results on the Harary index of a graph. These results mainly concern external graphs with respect to the Harary index; the relations to other topological indices; its properties and applications to pure graph theory and chemical graph theory; and two significant variants, i. e. , additively and multiplicatively weighted Harary indices. In the last chapter, we present a number of open problems related to the Harary index. As such, the book will not only be of interest to graph researchers, but to mathematical chemists as well.
