books.google.com - The theory of vertex operator algebras is showing its power in the solution of concrete mathematical problems as well as in the comprehension of conceptual structures of conformal field theories. This book formulates and proves the equivalence between the algebraic and geometric formulations of the notion...http://books.google.com/books/about/Two_Dimensional_Conformal_Geometry_and_V.html?id=SUUdknTpYjEC&utm_source=gb-gplus-shareTwo-Dimensional Conformal Geometry and Vertex Operator Algebras
