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…

Quantum cohomology of minuscule homogeneous spaces II : Hidden symmetries

Pierre-Emmanuel Chaput, Laurent Manivel, Nicolas Perrin

We prove that the quantum cohomology ring of any minuscule or cominuscule homogeneous space, once localized at the quantum parameter, has a non trivial involution mapping Schubert…

Quantum cohomology of minuscule homogeneous spaces

Pierre-Emmanuel Chaput, Laurent Manivel, Nicolas Perrin

We study the quantum cohomology of (co)minuscule homogeneous varieties under a unified perspective. We show that three points Gromov-Witten invariants can always be interpreted as…

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…
