报告摘要：

In this talk, we first determine the automorphism group of the twisted Heisenberg-Virasoro vertex operator algebra V_L(l_{123},0). Then, for any integer t>1, we introduce a new Lie algebra L_t, and show that \sigma_t-twisted V_L(l_{123},0) (l_2=0)-modules are in one-to-one correspondence with restricted L_t-modules of level l_{13}, where \sigma_t is an order t automorphism of V_L(l_{123},0). At the end, we give a complete list of irreducible \sigma_t-twisted V_L(l_{123},0) (l_{2}=0)-modules.
