Unitary modules for the twisted Heisenberg-Virasoro algebra

摘要

In this paper, the conjugate-linear anti-involutions and the unitaryirreducible modules of the intermediate series over the twistedHeisenberg-Virasoro algebra are classified respectively. We prove that anyunitary irreducible module of the intermediate series over the twistedHeisenberg-Virasoro algebra is of the form $\mathcal{A}_{a,b,c}$ for $a\in\mathbb{R}, b\in 1/2+\sqrt{-1}\mathbb{R}, c\in \mathbb{C}.$
