The Adventure of Numbers

Description

Numbers are fascinating. The fascination begins in childhood, when we first learn to count, and continues as we learn arithmetic, algebra, geometry, and so on. Eventually, we find that numbers not only help us to measure the world, but also to understand it and, to some extent, to control it. In The Adventure of Numbers, Gilles Godefroy unfolds a great adventure of the mind by examining our expanding understanding of numbers throughout history.

The development of mathematics has been punctuated by a need to reconsider what we mean by "numbers". It is often during these times that major shifts occur, for example when the Pythagoreans discovered irrational numbers or when imaginary numbers were needed to solve the cubic. Each jump takes place in a context, where mathematics itself is forced to ponder fundamental questions, many of which led to famous controversies.

Godefroy's adventure starts in the very early days of mathematics in Mesopotamia and leads to the present day. The adventure does not end there. Important questions and controversies remain today that deal with consistency and complexity or with what constitutes a proof. And the future will hold even more questions.

The author, Gilles Godefroy, is a member of the Institut de Mathematiques de Jussieu and Directeur de Recherches at the C.N.R.S. The book is suitable for independent study and supplementary reading and is recommended for undergraduates, graduate students, and researchers interested in the history of mathematics.

Moduli of Riemann Surfaces, Real Algebraic Curves,
and Their Superanalogs

Description

The space of all Riemann surfaces (the so-called moduli space) plays an important role in algebraic geometry and its applications to quantum field theory. The present book is devoted to the study of topological properties of this space and of similar moduli spaces, such as the space of real algebraic curves, the space of mappings, and also superanalogs of all these spaces.

The book can be used by researchers and graduate students working in algebraic geometry, topology, and mathematical physics.

Contents

Introduction
Moduli of Riemann surfaces, Hurwitz type spaces and their superanalogs
Moduli of real algebraic curves and their superanalogs. Differentials, spinors, and Jacobians of real curves
Spaces of meromorphic functions on complex and real algebraic curves

Stark's Conjectures: Recent Work and New Directions

Description

Stark's conjectures on the behavior of L-functions were formulated in the 1970s. Since then, these conjectures and their generalizations have been actively investigated. This has led to significant progress in algebraic number theory.

The current volume, based on the conference held at Johns Hopkins University (Baltimore, MD), represents the state-of-the-art research in this area. The first four survey papers provide an introduction to a majority of the recent work related to Stark's conjectures. The remaining six contributions touch on some major themes currently under exploration in the area, such as non-abelian and p-adic aspects of the conjectures, abelian refinements, etc. Among others, some important contributors to the volume include Harold M. Stark, John Tate, and Barry Mazur.

The book is suitable for graduate students and researchers interested in number theory.

Nonstandard Models of Arithmetic and Set Theory

Description

This is the proceedings of the AMS special session on nonstandard models of arithmetic and set theory held at the Joint Mathematics Meetings in Baltimore (MD). The volume opens with an essay from Haim Gaifman that probes the concept of non-standardness in mathematics and provides a fascinating mix of historical and philosophical insights into the nature of nonstandard mathematical structures. In particular, Gaifman compares and contrasts the discovery of nonstandard models with other key mathematical innovations, such as the introduction of various number systems, the modern concept of function, and non-Euclidean geometries.

Other articles in the book present results related to nonstandard models in arithmetic and set theory, including a survey of known results on the Turing upper bounds of arithmetic sets and functions. The volume is suitable for graduate students and research mathematicians interested in logic, especially model theory.

H. Gaifman -- Non-standard models in a broader perspective
