Galois bimodules and integrality of PI comodule algebras over invariants
Pavel Etingof
Let A be a comodule algebra for a finite dimensional Hopf algebra K over an algebraically closed field k, and let A^K be the subalgebra of invariants. Let Z be a central subalgebra…

Representations of Rational Cherednik algebras with minimal support and torus knots
Pavel Etingof, Eugene Gorsky, Ivan Losev
We obtain several results about representations of rational Cherednik algebras, and discuss their applications. Our first result is the Cohen-Macaulayness property (as modules over…

Semisimple Hopf actions on commutative domains
Pavel Etingof, Chelsea Walton
Let H be a semisimple (so, finite dimensional) Hopf algebra over an algebraically closed field k of characteristic zero and let A be a commutative domain over k. We show that if A…
