報告簡介:
We explain an equivalence of the twisted super Yangian $\mathrm{Y}^{tw}\big(\mathfrak{osp}{M|N}\big)$ in different presentations, which is a coideal sub-superalgebra of the super Yangian of the general linear Lie superalgebra $gl{M|N}$. We introduce the quantum Berezinian $\mathfrak{B}^{tw}(u)$ for $\mathrm{Y}^{tw}\big(\mathfrak{osp}_{M|N}\big)$ and prove that the coefficients of $\mathfrak{B}^{tw}(u)$ generate its center. An explicit formulation of $\mathfrak{B}^{tw}(u)$ will be presented in terms of RTT generators. Moreover, we prove analogues of the Liouville theorem and quantum Sylvester theorem for the quantum Berezinian $\mathfrak{B}^{tw}(u)$. This talk is based on joint work with Y. Wang and H. Zhang.
