本文讨论了没有辛解的辛簇。K3曲面上的半稳定无扭滑层的模空间和辛V-流形就是这样的变体。我们将证明辛簇的局部Torelli定理。还给出了一些关于辛奇点的结果。
This paper deals with symplectic varieties which do not have symplectic resolutions. Some moduli spaces of semi-stable torsion-free sheaves on a K3 surface, and symplectic V-manifolds are such varieties. We shall prove local Torelli theorem for symplectic varieties. Some results on symplectic singularities are also included.
