Maths HEP Lunchtime Seminars: Landau-Ginzburg models and open topological string theory
12 March 2010 13:00 in CM221
Matrix factorisations describe topological D-branes in N=2 supersymmetric Landau-Ginzburg models. I shall explain how this description arises and consequently use it to study open string states. In particular, employing the theory of cyclic A-infinity-algebras allows to explicitly construct all tree-level amplitudes.
