3:45PM: AuslanderReiten duality for commutative rings: a survey of some recent developmentsHailong DaoLet R be a local Gorenstein ring with an isolated singularity. The AuslanderReiten duality is a duality between certain Extgroups of (M,N) where M,N are maximal CohenMacaulay modules over R. In this talk I will describe this duality and give an elementary proof. Then I will discuss possible extensions and the connection to the KapustinLi formula for matrix factorizations (when the ring is a hypersurface).
