N=2 minimal conformal field theories and matrix bifactorisations of x^d
Alexei Davydov, Ana Ros Camacho, Ingo Runkel
We prove a tensor equivalence between full subcategories of a) graded matrix factorisations of the potential x^d-y^d and b) representations of the N=2 minimal super vertex operator…

State sum construction of two-dimensional topological quantum field theories on spin surfaces
Sebastian Novak, Ingo Runkel
We provide a combinatorial model for spin surfaces. Given a triangulation of an oriented surface, a spin structure is encoded by assigning to each triangle a preferred edge, and to…
