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 $R_{u}^{X, d}$ denote the unipotent radical of a (proper) maximal standard parabolic subgroup of the classical group $Sp_{2 n} (q)$ , $SO_{2 n} (q)$ , 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.…

Transposed Poisson structures on Schrodinger algebra in (n+1)-dimensional space-time

Yang Yang, Xiaomin Tang, Abror Khudoyberdiyev

Transposed Poisson structures on the Schrödinger algebra in $(n + 1)$ -dimensional space-time of Schrödinger Lie groups are described. It was proven that the Schrödinger algebra $\mat…

Finite-dimensional irreducible $□_{q}$ -modules and their Drinfel'd polynomials

Yang Yang

Let $F$ denote an algebraically closed field with characteristic $0$ , and let $q$ denote a nonzero scalar in $F$ that is not a root of unity. Let $Z_{4}$ d…

Some $q$ -exponential formulas for finite-dimensional $□_{q}$ -modules

Yang Yang

We consider the algebra $□_{q}$ which is a mild generalization of the quantum algebra $U_{q} (sl_{2})$ . The algebra $□_{q}$ is defined by generators and relations. The ge…

Upper triangular matrices and Billiard Arrays

Yang Yang

Fix a nonnegative integer $d$ , a field $F$ , and a vector space $V$ over $F$ with dimension $d + 1$ . Let $T$ denote an invertible upper triangular matrix in ${\rm Ma…
