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 $δ$ -(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 modules of the planar Galilean conformal algebra from tensor products

Dashu Xu

This paper is devoted to constructing simple modules of the planar Galilean conformal algebra. We study the tensor products of finitely many simple $U (H)$ -free…

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 $Z$ -gradation allows the classificatio…

Radicals of weight one blocks of Ariki-Koike algebras

Yanbo Li, Dashu Xu

Let $K$ be a field and $q \in K$ , $q \neq = 0, 1$ . Let $H_{n} (q, Q)$ be an Ariki-Koike algebra, where the cyclotomic parameter $Q = (Q_{1}, Q_{2}, \dots, Q_{r}) \in K^{r}$ with $r\geq 2…
