Verma modules over deformed generalized Heisenberg-Virasoro algebras

Abstract

Let $\mathfrak g(G,\lambda)$ denote the deformed generalized Heisenberg-Virasoro algebra related to a complex parameter $\lambda\neq-1$ and an additive subgroup $G$ of $\mathbb C$. For a total order on $G$ that is compatible with addition, a Verma module over $\mathfrak g(G,\lambda)$ is defined. In this paper, we completely determine the irreducibility of these Verma modules.
