Tautological classes for (n,n+1) torus knots

Eugene Gorsky, Anton Mellit

We construct an explicit isomorphism between the HOMFLY-PT homology of torus knots and the direct sum of hook isotypic components of the space of diagonal coinvariants. A…

Positroid Links and Braid varieties

Roger Casals, Eugene Gorsky, Mikhail Gorsky +1

We study braid varieties and their relation to open positroid varieties. We discuss four different types of braids associated to open positroid strata and show that their associate…

Colored knot Floer homology: structures and examples

Akram Alishahi, Eugene Gorsky, Beibei Liu

Inspired by the colored version of Khovanov and Khovanov-Rozansky homology, we define a colored version of knot Floer homology by studying the colimit of a directed system of…

Stable deformed homology of torus knots

William Ballinger, Eugene Gorsky, Matthew Hogancamp +1

We compute the page in the Rasmussen spectral sequence from triply graded to Khovanov--Rozansky stable homology of torus knots. This confirms a weak form of…

The affine Springer fiber-sheaf correspondence

Eugene Gorsky, Oscar Kivinen, Alexei Oblomkov

Given a semisimple element in the loop Lie algebra of a reductive group, we construct a quasi-coherent sheaf on a partial resolution of the trigonometric commuting variety of the L…

Hecke categories, idempotents, and commuting stacks

Eugene Gorsky, Andrei Neguţ

We formulate a connection between a topological and a geometric category. The former is the idempotent completion of the (horizontal) trace of the affine Hecke category, while the…
