摘要In the deformation theory of coherent sheaves on algebraic varieties, it is natural to consider the case where the parameter algebra is allowed to be non-commutative. There are more NC deformations than the case of commutative base. The main problem is to determine the versal deformations for individual cases. We review some cases where the versal deformations are determined and applications.
