Abstract


Associated to any hypersurface singularity is a differential graded category of
matrix factorisations, which encapsulates homological invariants of the
singularity and has been an important example of a category of boundary
conditions in the context of topological field theory and topological string
theory. I will discuss the problem of calculating the A-infinity minimal model
of this differential graded category, and why this is important in the context
of deformation theory (of both singularities, and matrix factorisations).
