英文摘要
We have studied affine symplectic varieties and their crepant resolutions from the point of view of birational geometry and Poisson deformations.In particular, we proved that the Poisson deformations of affine symplectic varieties are unobstructed and we furthermore showed that those varieties have crepant resolutions if and only if they can be smoothed by Poisson deformations. We also gave a characterization of the nilpotent varieties of complex semisimple Lie algebras.
