Crepant partial resolutions of the nilpotent cone via Hamiltonian reduction

Gwyn Bellamy, Tom Gannon

We show that the nilpotent cone associated to a simply connected semisimple algebraic group, together with all its crepant projective partial resolutions, can be constructed as Ham…

The coordinate ring of the universal centralizer via Demazure operators

Tom Gannon, Victor Ginzburg

We give a simple description of the coordinate ring of the universal centralizer associated to a simply connected semisimple group. To this end, we prove a general result on Weil r…
