Abstract

The interpretation of D‐branes in terms of open strings has lead to much interest in boundary conditions of two‐dimensional conformal field theories (CFTs). These studies have deepened our understanding of CFT and allowed us to develop new computational tools. The construction of CFT correlators based on combining tools from topological field theory and non‐commutative algebra in tensor categories, which we summarize in this contribution, allows e.g. to discuss, apart from boundary conditions, also defect lines and disorder fields.

In this paper we study the structure of an abelian Hessian algebra. First we show that it can be decomposed into unital abelian Hessian algebras and a complete abelian Hessian algebra (abbreviated by CAHA). Then we show that a unital one is in fact a hyperbolic extension of a CAHA. Next we investiga

We study a symmetric Markov extension of k-algebras N → M, a certain kind of Frobenius extension with conditional expectation that is tracial on the centralizer and dual bases with a separability property. We place a depth two condition on this extension, which is essentially the requirement that th
