P. Deligne defined interpolations of the tensor category of representations of the symmetric group Sn to complex values of n. Namely, he defined tensor categories Rep(St) for any complex t. This construction was generalized by F. Knop to the case of wreath products of Sn with a finite group. Generalizing these results, we propose a method of interpolating representation categories of various algebras containing Sn (such as degenerate affine Hecke algebras, symplectic reflection algebras… 

Signatures of Stable Multiplicity Spaces in Restrictions of Representations of Symmetric Groups

Representation theory is a way of studying complex mathematical structures such as groups and algebras by mapping them to linear actions on vector spaces. Recently, Deligne proposed a new way to

FI-modules and stability for representations of symmetric groups

In this paper we introduce and develop the theory of FI-modules. We apply this theory to obtain new theorems about: - the cohomology of the configuration space of n distinct ordered points on an

FI-modules: a new approach to stability for S_n-representations

In this paper we introduce and develop the theory of FI-modules. We apply this theory to obtain new theorems about: • the cohomology of the configuration space of n distinct ordered points on an

Signatures of the Contravariant Form on Representations of the Hecke Algebra and Rational Cherednik Algebra associated to G(r,1,n)

The Hecke algebra and rational Cherednik algebra of the group G(r,1,n) are non-commutative algebras that are deformations of certain classical algebras associated to the group. These algebras have

Heisenberg Categorification and Wreath Deligne Category

We define a faithful linear monoidal functor from the partition category, and hence from Deligne’s category Rep(St), to the additive Karoubi envelope of the Heisenberg category. We show that the

AbstractThe theory of PBW properties of quadratic algebras, to which this paper aims to be a modest contribution, originates from the pioneering work of Drinfeld (see [Dr1]). In particular, as we

Classification of graded Hecke algebras for complex reflection groups

Abstract. The graded Hecke algebra for a finite Weyl group is intimately related to the geometry of the Springer correspondence. A construction of Drinfeld produces an analogue of a graded Hecke

On representations of rational Cherednik algebras in complex rank

We study a family of abelian categories O_{c, t} depending on complex parameters c, t which are interpolations of the O-category for the rational Cherednik algebra H_c(t) of type A, where t is a
