Multiparameter quantum Schur duality of type B

Quantum Algebra 2018-06-12 v2 Representation Theory

Abstract

We establish a Schur type duality between a coideal subalgebra of the quantum group of type A and the Hecke algebra of type B with 2 parameters. We identify the ı\imath-canonical basis on the tensor product of the natural representation with Lusztig's canonical basis of the type B Hecke algebra with unequal parameters associated to a weight function.
