Let H be the twisted Heisenberg–Virasoro algebra. In this paper, we first present a method to produce a class of tensor product H-modules, by which we can obtain the known weight H-modules M(V,Aα,b) and non-weight H-modules M(V,Ω(λ)). Then we study a class of linear tensor product non-weight modules M(V,Ω(λ0))i=1mΩ(λi,αi,βi) over H. The necessary and sufficient conditions for M(V,Ω(λ0))i=1mΩ(λi,αi,βi) to be irreducible are obtained. We also determine the necessary and sufficient conditions for two such irreducible H-modules to be isomorphic.

扭曲的Heisenberg–Virasoro代数上的Tensor产品模块

H是扭曲的Heisenberg–Virasoro代数。在本文中,我们首先提出一种产生一类张量积的方法H-模块,通过它我们可以获得已知的权重 H-模块 中号伏特一种αb 和非重量 H-模块 中号伏特Ωλ。然后我们研究一类线性张量积非权重模块中号伏特Ωλ0一世=1个Ωλ一世α一世β一世 超过 H。必要的充分条件中号伏特Ωλ0一世=1个Ωλ一世α一世β一世获得了不可约的。我们还确定了两个这样的不可约的充要条件H-模块是同构的。
