Twisted Yangians of types BI, CI, DI and Drinfeld type current relations
Vidas Regelskis
We study twisted Yangians associated with the split symmetric pairs of types BI, CI and DI. We introduce a new presentation of these algebras, which we call the transposed presenta…

Bethe vectors and recurrence relations for twisted Yangian based models
Vidas Regelskis
We study Olshanski twisted Yangian based models, known as one-dimensional "soliton non-preserving" open spin chains, by means of algebraic Bethe ansatz. The even case, when the bul…
