# Vertex Algebras and Algebraic Curves: Second Edition

Share this page
*Edward Frenkel; David Ben-Zvi*

Vertex algebras are algebraic objects that encapsulate the concept of
operator product expansion from two-dimensional conformal field theory. Vertex
algebras are fast becoming ubiquitous in many areas of modern mathematics, with
applications to representation theory, algebraic geometry, the theory of finite
groups, modular functions, topology, integrable systems, and combinatorics.

This book is an introduction to the theory of vertex algebras with a
particular emphasis on the relationship with the geometry of algebraic
curves. The notion of a vertex algebra is introduced in a
coordinate-independent way, so that vertex operators become well defined on
arbitrary smooth algebraic curves, possibly equipped with additional data, such
as a vector bundle. Vertex algebras then appear as the algebraic objects
encoding the geometric structure of various moduli spaces associated with
algebraic curves. Therefore they may be used to give a geometric interpretation
of various questions of representation theory.

The book contains many original results, introduces important new concepts,
and brings new insights into the theory of vertex algebras. The authors have
made a great effort to make the book self-contained and accessible to readers
of all backgrounds. Reviewers of the first edition anticipated that it would
have a long-lasting influence on this exciting field of mathematics and would
be very useful for graduate students and researchers interested in the
subject.

This second edition, substantially improved and expanded, includes several
new topics, in particular an introduction to the Beilinson-Drinfeld theory of
factorization algebras and the geometric Langlands correspondence.

The book is suitable for graduate students and research mathematicians
interested in representation theory, algebraic geometry, and mathematical
physics. For more information, visit www.math.berkeley.edu/ frenkel/book.
