Cohomological supports over derived complete intersections and local rings
Josh Pollitz
A theory of cohomological support for pairs of DG modules over a Koszul complex is investigated. These specialize to the support varieties of Avramov and Buchweitz defined over a c…

Equivariant isomorphisms of Ext and Tor modules
Josh Pollitz
In this article we establish equivariant isomorphisms of Ext and Tor modules over different relative complete intersections. More precisely, for a commutative ring , this paper…
