Biderivations of the twisted Heisenberg-Virasoro algebra and their applications
Xiaomin Tang, Xiaotong Li
In this paper, the biderivations without the skew-symmetric condition of the twisted Heisenberg-Virasoro algebra are presented. We find some non-inner and non-skew-symmetric bideri…

Post-Lie algebra structures on the Witt algebra
Xiaomin Tang
In this paper, we characterize the graded post-Lie algebra structures and a class of shifting post-Lie algebra structures on the Witt algebra. We obtain some new Lie algebras and g…
