# Quaternion Orders, Quadratic Forms, and Shimura Curves

A co-publication of the AMS and Centre de Recherches Mathématiques

Shimura curves are a far-reaching generalization of the
classical modular curves. They lie at the crossroads of many areas,
including complex analysis, hyperbolic geometry, algebraic geometry,
algebra, and arithmetic. This monograph presents Shimura curves from a
theoretical and algorithmic perspective.

The main topics are Shimura curves defined over the rational number
field, the construction of their fundamental domains, and the
determination of their complex multiplication points. The study of
complex multiplication points in Shimura curves leads to the study of
families of binary quadratic forms with algebraic coefficients and to
their classification by arithmetic Fuchsian groups. In this regard,
the authors develop a theory full of new possibilities that parallels
Gauss' theory on the classification of binary quadratic forms with
integral coefficients by the action of the modular group.

This is one of the few available books explaining the theory of
Shimura curves at the graduate student level. Each topic covered in
the book begins with a theoretical discussion followed by carefully
worked-out examples, preparing the way for further
research.

Titles in this series are co-published with the Centre de Recherches Mathématiques.
