Value Distributions of L-Functions

Series: Lecture Notes in Mathematics, Vol. 1877
2005, Approx. 270 p., Softcover
ISBN: 3-540-26526-0

About this book

These notes present recent results in the value-distribution theory of L-functions with emphasis on the phenomenon of universality. In 1975, Voronin proved that any non-vanishing analytic function can be approximated uniformly by certain shifts of the Riemann zeta-function in the critical strip. This spectacular universality property has a strong impact on the zero-distribution: Riemannfs hypothesis is true if and only if the Riemann zeta-function can approximate itself uniformly (in the sense of Voronin).

Meanwhile universality is proved for a large zoo of Dirichlet series, and it is conjectured that all reasonable L-functions are universal. In these notes we prove universality for polynomial Euler products. Our approach follows mainly Bagchi's probabilistic method. We further discuss related topics as, e.g., almost periodicity, density estimates, Nevanlinna theory, and functional independence.

The Geometry of an Art
The History of the Mathematical Theory of Perspective from Alberti to Monge

Series: Sources and Studies in the History of Mathematics and Physical Sciences
2005, Approx. 445 p. 604 illus., Hardcover
ISBN: 0-387-25961-9

About this book

This book aims at giving a comprehensive review of literature on perspective constructions from the Renaissance to the end of the eighteenth century. Covering the work of some 175 authors, it treats the emergence of the various methods of constructing perspective, the development of the theories underlying the constructions, the communication between mathematicians and artisans in these developments, and the interactions between these theories and various subjects in mathematical geometry. The main protagonists are Peiro della Francesca, Guidobaldo del Monte, Simon Stevin, Brook Taylor, and Johann Heinrich Lambert. The book includes a comprehensive bibliography of books and manuscripts on perspective.

Compact Lie Groups

Series: Graduate Texts in Mathematics, Vol. 235
2006, Approx. 180 p., Hardcover
ISBN: 0-387-30263-8

About this textbook

Blending algebra, analysis, and topology, the study of compact Lie groups is one of the most beautiful areas of mathematics and a key stepping stone to the theory of general Lie groups. Assuming no prior knowledge of Lie groups, this book covers the structure and representation theory of compact Lie groups. Included is the construction of the Spin groups, Schur Orthogonality, the Peter-Weyl Theorem, the Plancherel Theorem, the Maximal Torus Theorem, the Commutator Theorem, the Weyl Integration and Character Formulas, the Highest Weight Classification, and the Borel-Weil Theorem. The necessary Lie algebra theory is also developed in the text with a streamlined approach focusing on linear Lie groups.

A Concise Introduction to Mathematical Logic

Series: Universitext
2006, Approx. 255 p. 8 illus., Softcover
ISBN: 0-387-30294-8

About this textbook

Traditional logic as a part of philosophy is one of the oldest scientific disciplines. Mathematical logic, however, is a relatively young discipline and arose from the endeavors of Peano, Frege, Russell and others to create a logistic foundation for mathematics. It steadily developed during the 20th century into a broad discipline with several sub-areas and numerous applications in mathematics, informatics, linguistics and philosophy. While there are already several well-known textbooks on mathematical logic, this book is unique in that it is much more concise than most others, and the material is treated in a streamlined fashion which allows the professor to cover many important topics in a one semester course.

Although the book is intended for use as a graduate text, the first three chapters could be understood by undergraduates interested in mathematical logic. These initial chapters cover just the material for an introductory course on mathematical logic combined with the necessary material from set theory. This material is of a descriptive nature, providing a view towards decision problems, automated theorem proving, non-standard models and other subjects. The remaining chapters contain material on logic programming for computer scientists, model theory, recursion theory, Godelfs Incompleteness Theorems, and applications of mathematical logic. Philosophical and foundational problems of mathematics are discussed throughout the text. The author has provided exercises for each chapter, as well as hints to selected exercises.

Deformations of Algebraic Schemes

Series: Grundlehren der mathematischen Wissenschaften, Vol. 334
2006, Approx. 300 p., Hardcover
ISBN: 3-540-30608-0

About this book

The study of small and local deformations of algebraic varieties originates in the classical work of Kodaira and Spencer and its formalization by Grothendieck in the late 1950's. It has become increasingly important in algebraic geometry in every context where variational phenomena come into play, and in classification theory. Today deformation theory is highly formalized and has ramified widely. This self-contained account of deformation theory in classical algebraic geometry (over an algebraically closed field) brings together for the first time some results previously scattered in the literature, with relatively little known proofs, yet of everyday relevance to algebraic geometers. It also includes applications to the construction and properties of Severi varieties of families of plane nodal curves, space curves, deformations of quotient singularities, Hilbert schemes of points, local Picard functors, etc. The exposition, amenable at graduate student level. includes many examples.
