书本介绍：

This book provides a comprehensive introduction to the mathematical foundations of eco-
nomics, from basic set theory to fixed point theorems and constrained optimization. Rather
than simply offer a collection of problem-solving techniques, the book emphasizes the unifying
mathematical principles that underlie economics. Features include an extended presentation
of separation theorems and their applications, an account of constraint qualification in con-
strained optimization, and an introduction to monotone comparative statics. These topics are
developed by way of more than 800 exercises. The book is designed to be used as a graduate
text, a resource for self-study, and a reference for the professional economist. See the author’s
website (link at left) for additional information on this title, including solutions to each of the
845 exercises in the book.
