Local and Quasi Derivations of the Mirror Heisenberg-Virasoro Algebra
Shun Liu, Dashu Xu
We determine the generalized and local derivations of the mirror Heisenberg-Virasoro algebra. As a by-product, we give a complete characterization of -(bi)derivations.

Generalized superderivations of the super Virasoro algebras
Shun Liu, Dashu Xu
We explicitly determine the generalized superderivations of the Neveu-Schwarz and Ramond algebras.

Simple restricted modules of non-zero level over a deformed Heisenberg-Virasoro algebra
Shun Liu, Dashu Xu
We study representations of a deformed Heisenberg-Virasoro algebra that does not admit a triangular decomposition. Despite this, its -gradation allows the classificatio…
