Counting Lattice Paths Using Fourier Methods (Applied and Numerical Harmonic Analysis)
by Shaun Ault Charles KiceyThis monograph introduces a novel and effective approach to counting lattice paths by using the discrete Fourier transform (DFT) as a type of periodic generating function. Utilizing a previously unexplored connection between combinatorics and Fourier analysis, this method will allow readers to move to higher-dimensional lattice path problems with ease. The technique is carefully developed in the first three chapters using the algebraic properties of the DFT, moving from one-dimensional problems to higher dimensions. In the following chapter, the discussion turns to geometric properties of the DFT in order to study the corridor state space. Each chapter poses open-ended questions and exercises to prompt further practice and future research. Two appendices are also provided, which cover complex variables and non-rectangular lattices, thus ensuring the text will be self-contained and serve as a valued reference.Counting Lattice Paths Using Fourier Methods is ideal for upper-undergraduates and graduate students studying combinatorics or other areas of mathematics, as well as computer science or physics. Instructors will also find this a valuable resource for use in their seminars. Readers should have a firm understanding of calculus, including integration, sequences, and series, as well as a familiarity with proofs and elementary linear algebra.

Reelle Funktionen (Grundlehren der mathematischen Wissenschaften #68)
by Georg AumannDie Entwicklung, in welcher sich die Theorie der reellen Funktionen seit einiger Zeit befindet, betrifft vor allem die allgemeinen Begriffe. Besonders die Idee der Ordnung mit allen ihren Spielarten, wie sie etwa in den Strukturen des Filters, des Verbandes, des Somenringes und der Ortsfunktionen geprägt worden ist, führte in steigendem Maße zu einer Umgestaltung aller Teile der Theorie. Diese Entwicklung kann noch nicht als abgeschlossen angesehen werden; trotzdem wurde versucht, sie in diesem Buch zu berücksichtigen, zu dem Ausmaß allerdings, wie es mir ursprünglich vorschwebte, ist es nicht gekommen. Verspätet erst wurde mir die einschlägige Literatur zugänglich, und außerdem ergab es sich, daß der klassische Tatsachenbestand, der trotz aller neuen Be griffsbildungen immer noch den eigentlichen Schatz der Theorie aus macht, letzthin nicht vernachlässigt werden durfte. Daß auf den fol genden 400 Seiten keine erschöpfende Behandlung des Gesamtgebietes möglich war, ist bei der Weite desselben nicht verwunderlich. So fehlt insbesondere eine eingehende Behandlung der Theorien der Differen tiation der additiven Mengenfunktionen, der Oberflächenintegrale, des DENJoyschen Integrals, der CARATHEODoRYschen Ortsfunktionen und der SCHWARTzschen Distributionen; das Literaturverzeichnis am Ende des Buches mag ein kleiner Lückenbüßer dafür sein. Wegen der hier behandelten Gegenstände selbst aber verweise ich auf den nachfolgenden "Überblick".
Kreisgeometrie: Eine elementare Einführung (Springer-Lehrbuch)
by Günter AumannDie Kreisgeometrie eignet sich in idealer Weise, den Reichtum der Geometrie zu erschließen. Ausgehend von den klassischen, über 2000 Jahre alten Sätzen der Kreisgeometrie spannt der Autor den Bogen bis in die Neuzeit, in der neue, vor allem von Jacob Steiner entwickelte Werkzeuge der Kreisgeometrie einen enormem Schub brachten. Damit gelingt es ihm, ein breites Themenspektrum anzusprechen, das nicht nur viele berühmte Sätze, sondern auch zahlreiche kaum bekannte Resultate umfasst.Um die Beweisideen und deren geometrischen Kern transparent zu machen, steht bei allen Beweisen die geometrische Argumentation im Vordergrund.Über 250 Abbildungen und ein lockerer, aber präziser Schreibstil begleiten den Leser bei dieser faszinierenden Reise durch die Kreisgeometrie.
Values of Non-Atomic Games
by Robert J. Aumann Lloyd S. ShapleyThe "Shapley value" of a finite multi- person game associates to each player the amount he should be willing to pay to participate. This book extends the value concept to certain classes of non-atomic games, which are infinite-person games in which no individual player has significance. It is primarily a book of mathematics—a study of non-additive set functions and associated linear operators.Originally published in 1974.The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Symplectic 4-Manifolds and Algebraic Surfaces: Lectures given at the C.I.M.E. Summer School held in Cetraro, Italy, September 2-10, 2003 (Lecture Notes in Mathematics #1938)
by Denis Auroux Fabrizio Catanese Marco Manetti Paul Seidel Bernd Siebert Ivan Smith Gang TianModern approaches to the study of symplectic 4-manifolds and algebraic surfaces combine a wide range of techniques and sources of inspiration. Gauge theory, symplectic geometry, pseudoholomorphic curves, singularity theory, moduli spaces, braid groups, monodromy, in addition to classical topology and algebraic geometry, combine to make this one of the most vibrant and active areas of research in mathematics. It is our hope that the five lectures of the present volume given at the C.I.M.E. Summer School held in Cetraro, Italy, September 2-10, 2003 will be useful to people working in related areas of mathematics and will become standard references on these topics. The volume is a coherent exposition of an active field of current research focusing on the introduction of new methods for the study of moduli spaces of complex structures on algebraic surfaces, and for the investigation of symplectic topology in dimension 4 and higher.
Algebra, Geometry, and Physics in the 21st Century: Kontsevich Festschrift (Progress in Mathematics #324)
by Denis Auroux Ludmil Katzarkov Tony Pantev Yan Soibelman Yuri TschinkelThis volume is a tribute to Maxim Kontsevich, one of the most original and influential mathematicians of our time. Maxim’s vision has inspired major developments in many areas of mathematics, ranging all the way from probability theory to motives over finite fields, and has brought forth a paradigm shift at the interface of modern geometry and mathematical physics. Many of his papers have opened completely new directions of research and led to the solutions of many classical problems. This book collects papers by leading experts currently engaged in research on topics close to Maxim’s heart. Contributors: S. Donaldson A. Goncharov D. Kaledin M. Kapranov A. Kapustin L. Katzarkov A.

Boundary Value Problems and Hardy Spaces for Elliptic Systems with Block Structure (Progress in Mathematics #346)
by Pascal Auscher Moritz EgertIn this monograph, for elliptic systems with block structure in the upper half-space and t-independent coefficients, the authors settle the study of boundary value problems by proving compatible well-posedness of Dirichlet, regularity and Neumann problems in optimal ranges of exponents. Prior to this work, only the two-dimensional situation was fully understood. In higher dimensions, partial results for existence in smaller ranges of exponents and for a subclass of such systems had been established. The presented uniqueness results are completely new, and the authors also elucidate optimal ranges for problems with fractional regularity data. The first part of the monograph, which can be read independently, provides optimal ranges of exponents for functional calculus and adapted Hardy spaces for the associated boundary operator. Methods use and improve, with new results, all the machinery developed over the last two decades to study such problems: the Kato square root estimates and Riesz transforms, Hardy spaces associated to operators, off-diagonal estimates, non-tangential estimates and square functions, and abstract layer potentials to replace fundamental solutions in the absence of local regularity of solutions.
The Making of a New Science: A Personal Journey Through the Early Years of Theoretical Computer Science
by Giorgio AusielloThis book explains the development of theoretical computer science in its early stages, specifically from 1965 to 1990. The author is among the pioneers of theoretical computer science, and he guides the reader through the early stages of development of this new discipline. He explains the origins of the field, arising from disciplines such as logic, mathematics, and electronics, and he describes the evolution of the key principles of computing in strands such as computability, algorithms, and programming.But mainly it's a story about people – pioneers with diverse backgrounds and characters came together to overcome philosophical and institutional challenges and build a community. They collaborated on research efforts, they established schools and conferences, they developed the first related university courses, they taught generations of future researchers and practitioners, and they set up the key publications to communicate and archive their knowledge. The book is a fascinating insight into the field as it existed and evolved, it will be valuable reading for anyone interested in the history of computing.
