K-theoretic construction of affine quantum Schur algebras and iquantum groups with unequal parameters
Li Luo, Zheming Xu, Yang Yang
We present an equivariant K-theoretic construction of affine quantum Schur algebras of type C with three parameters by taking advantage of Kato's exotic framework. This enables the…
Twisted Yangians and Steinberg varieties of type C
Changjian Su, Yang Yang
We study the equivariant homology of the generalized Steinberg variety of type C and show that there exists a surjective algebra homomorphism from the twisted Yangian of type $\AII…
Polynomial properties of unipotent radicals of parabolic subgroups in classical groups
Qingchun Hao, Yang Yang
Let denote the unipotent radical of a (proper) maximal standard parabolic subgroup of the classical group , , or $\mathrm U_{2…
Geometric construction of Schur algebras
Li Luo, Zheming Xu, Yang Yang
We provide the geometric construction of a series of generalized Schur algebras of any type via Borel-Moore homologies and equivariant K-groups of generalized Steinberg varieties.…
