Abstract:
A certain generalisation of spaces of conformal blocks, due to Lyubashenko, can be constructed from a Hopf algebra in a braided category that is not necessarily semisimple. I will describe how algebraic data of a conformal field theory provides other similar categorical constructions. In particular, the category of modules of an algebra in a braided category gives a (non-unital) bialgebra in the same category.
