Twisted equivariant HKR theorem for torus action and the small quantum group

Nicolas Hemelsoet

We show that when a torus $T$ acts on a smooth variety $X$ , the twisted HKR isomorphism is equivariant. The main consequence is that the Bezrukavnikov- Lachowska isomorphism, relat…

On the affine Springer fibers inside the invariant center of the small quantum group

Nicolas Hemelsoet, Oscar Kivinen, Anna Lachowska

Let $u_{ζ}^{\lor}$ denote the small quantum group associated with a simple Lie algebra $g^{\lor}$ and a root of unity $ζ$ . In [9], a geometric realization of $Z(\ma…
