Description
Many aspects of algebra and representation theory can be generalized from
the category of vector spaces to more general categories. In fact,
super-mathematics is based on such a generalization of standard mathematical
constructions to the category of super-vector spaces. It has recently been
realized that conformal field theories in two dimensions, i.e. the quantum
field theories on the worldsheet of a string, can be understood as the theory
of (Frobenius-)algebras in certain categories, so-called modular tensor
categories.
