Structures of not-finitely graded Lie algebras related to generalized Heisenberg-Virasoro algebras
Guangzhe Fan, Chenhong Zhou, Xiaoqing Yue
In this paper, we study the structure theory of a class of not-finitely graded Lie algebras related to generalized Heisenberg-Virasoro algebras. In particular, the derivation algeb…
