Derivations and Biderivations of affine-Virasoro Lie algebras
Priyanshu Chakraborty, Yufeng Yao, Kaiming Zhao
In this paper we determine all derivations and biderivations of an affine-Virasoro Lie algebra associated with a finite-dimensional complex simple Lie algebra . We pr…

Simple smooth modules over the Ramond algebra and applications to vertex operator superalgebras
Yulu Chen, Yufeng Yao, Kaiming Zhao
Simple smooth modules over the Virasoro algebra and one of the super-Virasoro algebras, named the Neveu-Schwarz algebra, have been classified. This problem remained unsolved for th…
