RELATION ALGEBRAS

Included in series
Studies in Logic and the Foundations of Mathematics, 150

Description

*The modern theory of algebras of binary relations, reformulated by Tarski as an abstract, algebraic, equational theory of relation algebras, has considerable mathematical significance, with applications in various fields: e.g., in computer science---databases, specification theory, AI---and in anthropology, economics, physics, and philosophical logic.?

*This comprehensive treatment of the theory of relation algebras and the calculus of relations is the first devoted to a systematic development of the subject.?

Key Features:

- Presents historical milestones from a modern perspective.
- Careful, thorough, detailed guide to understanding relation algebras.
- Includes a wealth of scholarly material --- 100 years of work by a research community --- presented in book form for the first time.
- Provides a framework and unified perspective of the subject.
- Roger D. Maddux is one of the world's leading experts in the field of relation algebras.

About this book

This book intends to give an extensive treatment of the basic theory of general near polygons. Near polygons have been introduced about 25 years ago and have been studied intensively in the 1980s. In recent years the subject of near polygons has regained interest. This book discusses old and new results on this subject. In the first part of the book, we develop the basic theory of near polygons. We discuss three important classes of near polygons (dense, regular and glued near polygons) and develop the theory of valuations which is very important for classification purposes. In the second part of the book, we discuss recent results on the classification of dense near polygons with three points on each line.

About this book

The study of variational problems in materials science has a long history, and it has contributed a lot in shaping our understanding on how materials work and perform. There is, however, a recent renewed interest in this subject as a consequence of the fruitful interaction between mathematical analysis and the modelling of new, technologically advanced materials.

This volume collects articles about the study of BV vector fields, path functionals over Wasserstein spaces, variational approaches to quasi-static evolution, free-discontinuity problems with applications to fracture and plasticity, systems with hysteresis or with interfacial energies, evolution of interfaces, multi-scale analysis in ferromagnetism and ferroelectricity, variational techniques for the study of crystal plasticity, of dislocations, and of concentrations in Ginzburg-Landau functionals, concentrated contact interactions, and phase transitions in biaxial liquid crystals.

Topics in the Theory of Algebraic Function Fields

About this textbook

Algebraic function fields of one variable are used in several areas of mathematics: complex analysis, algebraic geometry, and number theory. This text applies an arithmetic-algebraic viewpoint to the study of function fields as part of the algebraic theory of numbers, where a function field of one variable is the analogue of a finite extension of Q, the field of rational numbers. The author does not ignore the geometric and analytic aspects of function fields, but focuses on an in-depth examination from a number-theoretic perspective.
