%0 Journal Article %T Structures of not-finitely graded Lie algebras related to generalized Virasoro algebras %A Qiufan Chen %A Jianzhi Han %A Yucai Su %J Mathematics %D 2014 %I arXiv %X In this paper, we study the structure theory of a class of not-finitely graded Lie algebras related to generalized Virasoro algebras. In particular,the derivation algebras, the automorphism groups and the second cohomology groups of these Lie algebras are determined. %U http://arxiv.org/abs/1404.3279v1
