Irreducible twisted Heisenberg-Virasoro modules from tensor products

Abstract

In this paper, we realize polynomial $\H$-modules $\Omega (\lambda ,\alpha ,\beta )$ from irreducible twisted Heisenberg-Virasoro modules $\A_{α,β}$. It follows from $\H$-modules $\Omega (\lambda ,\alpha ,\beta )$ and $\mathrm{Ind}(M)$ that we obtain a class of natural non-weight tensor product modules $({⨂}_{i=1}^m\Omega ({\lambda }_i,{\alpha }_i,{\beta }_i))\otimes \mathrm{Ind}(M)$. Then we give the necessary and sufficient conditions under which these modules are irreducible and isomorphic, and also give that the irreducible modules in this class are new.
