On Cohen-Macaulayness of S_n-invariant subspace arrangements
Aaron Brookner, David Corwin, Pavel Etingof +1
Given a partition of n, consider the subspace of where the first coordinates are equal, the next coordinates are equal, etc. In this paper, we study sub…
Semisimple Hopf actions on Weyl algebras
Juan Cuadra, Pavel Etingof, Chelsea Walton
We study actions of semisimple Hopf algebras H on Weyl algebras A over a field of characteristic zero. We show that the action of H on A must factor through a group algebra; in oth…
Representation theory in complex rank, II
Pavel Etingof
This paper is a sequel to arXiv:1401.6321. We define and study representation categories based on Deligne categories Rep(GL_t), Rep(O_t), Rep(Sp_2t), where t is any (non-integer) c…
Representation theory in complex rank, I
Pavel Etingof
P. Deligne defined interpolations of the tensor category of representations of the symmetric group S_n to complex values of n. Namely, he defined tensor categories Rep(S_t) for any…
Pointed Hopf actions on fields, I
Pavel Etingof, Chelsea Walton
Actions of semisimple Hopf algebras H over an algebraically closed field of characteristic zero on commutative domains were classified recently by the authors. The answer turns out…
Invariants of Hamiltonian flow on locally complete intersections
Pavel Etingof, Travis Schedler
We consider the Hamiltonian flow on complex complete intersection surfaces with isolated singularities, equipped with the Jacobian Poisson structure. More generally we consider com…
