Theory and Representations of
Conformal Algebras
ABSTRACT:
Conformal
superalgebras establish a rigorous algebraic foundation for the theory
of vertex algebras and, more generally, conformal field theory. In
particular, they are closely related (and generalize) the
superconformal algebras known to physicists. More generally, conformal
algebras provide a powerful formalism for the study of
infinite-dimensonal Lie algebras and their representations. I
will discuss the recently obtained classification of finite conformal
superalgebras and explain what makes some of them suitable for physical
theories. Then I will describe the general set-up for "conformal
representation theory" and related combinatorial and algebraic problems.
