Introduction to Vertex Operator Algebras and Their Representations [Hardcover]

* Introduces the fundamental theory of vertex operator algebras and its basic techniques and examples.

* Begins with a detailed presentation of the theoretical foundations and proceeds to a range of applications.

* Includes a number of new, original results and brings fresh perspective to important works of many other researchers in algebra, lie theory, representation theory, string theory, quantum field theory, and other areas of math and physics.
