We show that all quantum symmetric pair coideal subalgebras Bc of Kac-Moody type have a bar involution for a suitable choice of parameters c. The proof relies on a generalized notion of quasi K-matrix. The proof does not involve an explicit presentation of Bc in terms of generators and relations. 
Defining relations of quantum symmetric pair coideal subalgebras
Abstract We explicitly determine the defining relations of all quantum symmetric pair coideal subalgebras of quantised enveloping algebras of Kac–Moody type. Our methods are based on star products on
Quantum symmetric pairs
This is a survey of some recent progress on quantum symmetric pairs and applications. The topics include quasi K-matrices, ıSchur duality, canonical bases, super Kazhdan-Lusztig theory, ıHall
Pseudo-symmetric pairs for Kac-Moody algebras
Lie algebra involutions and their fixed-point subalgebras give rise to symmetric spaces and real forms of complex Lie algebras, and are well-studied in the context of symmetrizable KacMoody algebras.
Universal K-matrices for quantum Kac-Moody algebras
We introduce the notion of a cylindrical bialgebra, which is a quasitriangular bialgebra H H endowed with a universal K-matrix, i.e., a universal solution of a generalized reflection
Rational K-matrices for finite-dimensional representations of quantum affine algebras
. Let g be a complex simple Lie algebra. We prove that every finite-dimensional representation of the (untwisted) quantum affine algebra U q L g gives rise to a family of spectral K-matrices, namely
Stability of $\imath$canonical bases of irreducible finite type of real rank one
. It has been known since their birth in Bao and Wang’s work that the ı canonical bases of ı quantum groups are not stable in general. In the author’s previ-ous work, the stability of ı canonical


Let (U, ) be a quasi-split quantum symmetric pair of arbitrary Kac–Moody type, where “quasi-split” means the corresponding Satake diagram contains no black node. We give a presentation of the group
The bar involution for quantum symmetric pairs
We construct a bar involution for quantum symmetric pair coideal subalgebras $B_{\mathbf{c},\mathbf{s}}$ corresponding to involutive automorphisms of the second kind of symmetrizable Kac-Moody
Factorisation of quasi K-matrices for quantum symmetric pairs
The theory of quantum symmetric pairs provides a universal K-matrix which is an analog of the universal R-matrix for quantum groups. The main ingredient in the construction of the universal
Symmetric Pairs for Quantized Enveloping Algebras
Abstract Let θ be an involution of a semisimple Lie algebra g , let g θ denote the fixed Lie subalgebra, and assume the Cartan subalgebra of g has been chosen in a suitable way. We construct a
We describe how certain cyclotomic Nazarov-Wenzl algebras occur as endomorphism rings of projective modules in a parabolic version of BGG category O of type D. Furthermore we study a family of
Introduction to Quantum Groups
We give an elementary introduction to the theory of algebraic and topological quantum groups (in the spirit of S. L. Woronowicz). In particular, we recall the basic facts from Hopf (*-) algebra
Quasitriangular coideal subalgebras of Uq(g) in terms of generalized Satake diagrams
Let g be a finite‐dimensional semisimple complex Lie algebra and θ an involutive automorphism of g . According to Letzter, Kolb and Balagović the fixed‐point subalgebra k=gθ has a quantum counterpart
