LandauGinzburg
On the geometry and (bi)category theory of isolated hypersurface singularities. Currently on hiatus.
The aim of the seminar is to provide an accessible and detailed construction of the bicategory of LandauGinzburg models (which has isolated hypersurface singularities as objects and matrix factorisations as 1morphisms). Partly this is meant as background for work on semantics of linear logic involving this structure. You might the talking boards in LC001 useful.
 Organiser: Daniel Murfet.
 Venue: the Rising Sea.
