Hodge diamonds of the Landau--Ginzburg orbifolds

Alexey Basalaev, Andrei Ionov

Consider the pairs $(f, G)$ with $f = f (x_{1}, \dots, x_{N})$ being a polynomial defining a quasihomogeneous singularity and $G$ being a subgroup of $SL (N, C)$ , preserving $…

Equivariant derived category of a reductive group as a categorical center

Roman Bezrukavnikov, Andrei Ionov, Kostiantyn Tolmachov +1

We prove that the adjoint equivariant derived category of a reductive group $G$ is equivalent to the appropriately defined monoidal center of the torus-equivariant version of the H…

Tilting sheaves for real groups and Koszul duality

Andrei Ionov, Zhiwei Yun

For a certain class of real analytic varieties with Lie group actions we develop a theory of (free-monodromic) tilting sheaves, and apply it to flag varieties stratified by real gr…
