A new class of irreducible modules over the BMS-Kac-Moody algebra
Qiu-Fan Chen, Yi-Jun Bai
In this paper, we construct a class of non-weight modules over the BMS-Kac-Moody algebra by taking tensor products of finitely many irreducible modules $Φ(λ,\a,\b,\r,h(t))$ with ir…

Non-weight modules over the BMS-Kac-Moody algebra
Qiufan Chen, Cong Guo
In this paper, we construct and classify a class of non-weight modules over the BMS-Kac-Moody algebra, which are free modules of rank one when restricted to the universal envelopin…

Tensor product weight modules over the affine-Virasoro algebra
Qiu-Fan Chen, Yu-Feng Yao
In this paper, we study the tensor products of irreducible highest weight modules with irreducible loop modules over the affine-Virasoro algebra with aid of the ``shifting techniqu…
