内容摘要:
We explain an equivalence of the twisted super Yangian Ytw(ospM|N) in different presentations, which is a coideal sub-superalgebra of the super Yangian of the general linear Lie superalgebra glM|N. We introduce the quantum Berezinian Btw(u) for Ytw(ospM|N) and prove that the coefficients of Btw(u) generate its center. An explicit formulation of Btw(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 Btw(u). This talk is based on joint work with Hongda Lin and Honglian Zhang.
