|Title||A-infinity categories of matrix factorisations|
|Presenter||Daniel Murfet (The University of Melbourne)|
|Session||Category Theory, Algebraic Topology, K-Theory|
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).
