A perspective projection of a dodecahedral tessellation in H3. Four dodecahedra meet at each edge, and eight meet at each vertex, like the cubes of a cubic tessellation in E3.

Title: Matrix Factorisations and Knörrer Periodicity

Speaker: Edwin Hollands

Abstract:Knörrer Periodicity is an idea that originated in algebra, where matrix factorisations were used to study maximal Cohen-Macaulay modules. More recently, Orlov reinterpreted the result geometrically using the equivalence between matrix factorisations and derived singularity categories of hypersurfaces. I will recount some of this history, give some explanation of the result and then propose a new formulation as a special case of a certain deformation.

Some snacks will be provided before and after the talk.
