Title: Categorical approach to deformation theory
Date: Tue, Nov 24, 2015, 13:15 - 14:45
Place: Seminar Room B
Abstract: I will recall Schlessinger's infinitesimal deformation theory and generalise it to non-commutative deformation theory of a quasi-coherent sheaf on a scheme. I will then propose a further generalisation to non-commutative deformation theory of n sheaves. I will also present a categorical point of view on non-commutative deformation theory of n objects in an arbitrary abelian category. It is a joint work with A. Bondal.
