Non-commutative Deformations of Simple Objects in a Category of Perverse Coherent Sheaves

Abstract:
We explain general theory of multi-pointed non-commutative deformations of simple collections, and calculate some versal deformations in abelian categories of perverse coherent sheaves arising from tilting bundles for projective morphisms.
