Symplectic Resolutions for Coverings of Nilpotent Orbits
Baohua Fu
Let $\0$ be a nilpotent orbit in a semisimple complex Lie algebra $\g$. Denote by the simply connected Lie group with Lie algebra $\g$. For a -homogeneous covering $M \to \0…

Symplectic Resolutions for Quotient Singularities
Baohua Fu
We give some necessary conditions for the existence of a symplectic resolution for quotient singularities. The McKay correspondence is also worked out for these resolutions.

Factorization of Symmetric Matrices and Actions on Σ_k
Baohua Fu
In this note, firstly we give an easy proof of the factorization of symmetric matrices (see [Mos] math-ph/0203023), then we use it to prove the well-known fact that the automorphis…
