Description

I will discuss Landau-Ginzburg models with possibly different superpotentials glued together along one-dimensional defect lines. Defects preserving B-type supersymmetry can be represented by matrix factorisations of the difference of the superpotentials. The composition of these defects and their action on B-type boundary conditions is desribed in this framework. As an example I will discuss N=2 minimal models and compare to results from conformal field theory.
