On non-commutative deformations and applications to perverse coherent sheaves and semi-orthogonal decompositions Yujiro Kawamata |
|||
Abstract: We consider deformations of objects over non-commutative rings, which is more natural than commutative ones in some cases. We consider examples, and applications to perverse coherent sheaves, and semi-orthogonal decompositions of derived categories corresponding to singularities. Language: English |
