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…

2-Local derivations on a Block-type Lie algebra
Qiufan Chen, Xiaohan Guo
The present paper is devoted to study 2-local derivations on the Block-type Lie algebra which is an infinite-dimensional Lie algebra with some outer derivations. We prove that ever…

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…
