We formulate a family of algebras, twisted Yangians (of simply-laced quasi-split type) in
Drinfeld type current generators and defining relations. These new algebras admit PBW type …

This paper studies quantum symmetric pairs (U~, U~ ı) associated with quasi-split Satake
diagrams of affine type A 2 r-1, D r, E 6 with a nontrivial diagram involution fixing the affine …

Recently, relative braid group symmetries on ı quantum groups of arbitrary finite types have
been constructed by Wang and the author. In this paper, generalizing that finite-type …

We introduce a universal framework for boundary transfer matrices, inspired by Sklyanin's
two-row transfer matrix approach for quantum integrable systems with boundary conditions …

We construct a unique braid group action on deformed q-Weyl algebra A q (S)⁠. Under this
action, we give a realization of the braid group action on quasi-split ıquantum groups U (S) ı …

We formulate a precise connection between the new Drinfeld presentation of a quantum
affine algebra $ U_q\widehat {\mathfrak {g}} $ and the new Drinfeld presentation of affine …

This paper studies quantum symmetric pairs $(\widetilde {\mathbf U},\widetilde {{\mathbf
U}}^\imath) $ associated with quasi-split Satake diagrams of affine type $ A_ {2r-1}, D_r, E …

We provide a geometric realization of the quasi-split affine $\imath $ quantum group of type
AIII $ _ {2n-1}^{(\tau)} $ in terms of equivariant K-groups of non-connected Steinberg …

We construct a unique braid group action on modified $ q $-Weyl algebra $\mathbf A_q (S)
$. Under this action, we give a realization of the braid group action on quasi-split $\imath …
