Wreath products, nilpotent orbits and symplectic deformations
Baohua Fu
We recover a 4-dimensional wreath product X as a transversal slice to a nilpotent orbit in sp_6. By using deformations of Springer resolutions, we construct a symplectic deformatio…
On stratified Mukai flops
Pierre-Emmanuel Chaput, Baohua Fu
We construct a resolution of stratified Mukai flops of type A, D, E_{6, I} by successively blowing up smooth subvarieties. In the case of E_{6, I}, we construct a natural functor w…
Extremal contractions, stratified Mukai flops and Springer maps
Baohua Fu
We prove that two Springer maps over a nilpotent orbit closure with the same degree are connected by stratified Mukai flops and the latter is obtained by extremal contractions of a…
Contact resolutions of projectivised nilpotent orbit closures
Baohua Fu
The projectivised nilpotent orbit closure P(\bar{O}) carries a natural contact structure on its smooth part. A resolution X \to P(\bar{O}) is called contact if the contact structur…
