    • Pseudo-symmetric pairs for Kac-Moody algebras 

      Regelskis, Vidas; Vlaar, Bart (American Mathematical Society, 2022-08-31)
      Lie algebra involutions and their fixed-point subalgebras give rise to symmetric spaces and real forms of complex Lie algebras, and are wellstudied in the context of symmetrizable Kac-Moody algebras. In this paper we study ...

    • Quasitriangular coideal subalgebras of Uq(g) in terms of generalized Satake diagrams 

      Regelskis, Vidas; Vlaar, Bart (2020-08-01)
      Let (Formula presented.) be a finite-dimensional semisimple complex Lie algebra and (Formula presented.) an involutive automorphism of (Formula presented.). According to Letzter, Kolb and Balagović the fixed-point subalgebra ...
