Toroidal analogues of the Grothendieck-Springer map
Samuel DeHority
We study moduli spaces of objects in the derived category of noncommutative ruled surfaces over orbifold curves to find equivariant deformations of moduli spaces of framed sheaves…

Elliptic surfaces and toroidal superalgebras
Samuel DeHority
The equivariant cohomology of certain moduli spaces of sheaves on isotrivial elliptic surfaces are shown to admit representations of infinite dimensional Lie (super)algebras. The c…
