Twisted Yangians for symmetric pairs of types B, C, D
Nicolas Guay, Vidas Regelskis
We study a class of quantized enveloping algebras, called twisted Yangians, associated with the symmetric pairs of types B, C, D in Cartan's classification. These algebras can be r…

Drinfeld J Presentation of Twisted Yangians
Samuel Belliard, Vidas Regelskis
We present a quantization of a Lie coideal structure for twisted half-loop algebras of finite-dimensional simple complex Lie algebras. We obtain algebra closure relations of twiste…
