GKLO representations of twisted Yangians in type and quantizations of symmetric quotients of the affine Grassmannian
Robin Bartlett, Tomasz Przezdziecki, Lukas Tappeiner
We construct an analogue of Gerasimov-Kharchev-Lebedev-Oblezin (GKLO) representations for twisted Yangians of type , using the recently found current presentation of t…

Shifted twisted Yangians and Slodowy slices in classical Lie algebras
Lukas Tappeiner, Lewis Topley
In this paper we introduce the shifted twisted Yangian of type {\sf AI}, following the work of Lu--Wang--Zhang, and we study their semiclassical limits, a class of Poisson algebras…
