Fine gradings and their Weyl groups for twisted Heisenberg Lie superalgebras
Wenjuan Xie, Wende Liu
In this paper we define the so-called twisted Heisenberg superalgebras over the complex number field by adding derivations to Heisenberg superalgebras. We classify the fine grading…

Adjoint cohomology of two-step nilpotent Lie superalgebras
Wende Liu, Yong Yang, Xiankun Du
In this paper, we study the cup products and Betti numbers over cohomology superspaces of two-step nilpotent Lie superalgebras with coefficients in the adjoint modules over an alge…
