Yoshinori Namikawa
This is a local version of math.AG/0506534. We shall deal with the deformation of a convex symplectic variety instead of a projective one. The usual deformation does not work w…

On deformations of Q-factorial symplectic varieties
Yoshinori Namikawa
We shall prove that any small deformation of a Q-factorial projective symplectic variety with terminal singularities is locally rigid; in other words, it preserves the singularity.…
