Hochschild cohomology of Fermat type polynomials with non-abelian symmetries

Alexey Basalaev, Andrei Ionov

For a polynomial $f = x_{1}^{n} + \dots + x_{N}^{n}$ let $G_{f}$ be the non--abelian maximal group of symmetries of $f$ . This is a group generated by all $g \in GL (N, C)$ , r…

Filtrations on block subalgebras of reduced universal enveloping algebras

Andrei Ionov, Dylan Pentland

We study the interaction between the block decompositions of reduced universal enveloping algebras in positive characteristic, the PBW filtration, and the nilpotent cone. We provid…
