We establish a three-parameter Schur duality between the affine Hecke algebra
of type C and a coideal subalgebra of quantum affine Tex. At the
equal parameter specializations, we obtain Schur dualities of types BCD.

We study the representation theory of a quantum symmetric pair
Tex with two parameters Tex of type AIII, by
using highest weight theory and a variant of Kashiwara's crystal basis theory.
Namely, we classify the irr...

Texquantum groups are generalizations of quantum groups which appear as
coideal subalgebras of quantum groups in the theory of quantum symmetric pairs.
In this paper, we define the notion of classical weight modules over an
Texquantum gr...

In their study of the equivariant K-theory of the generalized flag varieties
Tex, where Tex is a complex semisimple Lie group, and Tex is a parabolic
subgroup of Tex, Lenart and Postnikov introduced a combinatorial tool, called
the alcove paths ...

In this paper, we study basic properties of global Tex-crystal bases for
integrable modules over a quantum symmetric pair coideal subalgebra
Tex associated to the Satake diagram of type AIII with even
white nodes and no blac...

We generalize a construction in [BW18] (arXiv:1610.09271) by showing that the
tensor product of a based Tex-module and a based
Tex-module is a based Tex-module. This is then used
to formulate a Kazhdan-...
