Pseudo-centralizers in affine Hecke algebras

Jonathan Gruber

We introduce and study a subalgebra $B$ of the affine Hecke algebra, which arises from a centralizer construction in the double affine Hecke algebra, and which may be reg…

Linkage and translation for tensor products of representations of simple algebraic groups and quantum groups

Jonathan Gruber

Let $G$ be either a simple linear algebraic group over an algebraically closed field of characteristic $ℓ > 0$ or a quantum group at an $ℓ$ -th root of unity. We define…
