Localization algebras and deformations of Koszul algebras
Tom Braden, Anthony Licata, Christopher Phan +2
We show that the center of a flat graded deformation of a standard Koszul algebra behaves in many ways like the torus-equivariant cohomology ring of an algebraic variety with finit…
Derived equivalences for cotangent bundles of Grassmannians via categorical sl(2) actions
Sabin Cautis, Joel Kamnitzer, Anthony Licata
We construct an equivalence of categories from a strong categorical sl(2) action, following the work of Chuang-Rouquier. As an application, we give an explicit, natural equivalence…
Coherent sheaves and categorical sl(2) actions
Sabin Cautis, Joel Kamnitzer, Anthony Licata
We introduce the concept of a geometric categorical sl(2) action and relate it to that of a strong categorical sl(2) action. The latter is a special kind of 2-representation in the…
Categorical geometric skew Howe duality
Sabin Cautis, Joel Kamnitzer, Anthony Licata
We categorify the R-matrix isomorphism between tensor products of minuscule representations of U_q(sl(n)) by constructing an equivalence between the derived categories of coherent…
