Derivations and Biderivations of affine-Virasoro Lie algebras
arXiv:2508.15573
Abstract
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 prove that all the derivations and biderivations of affine-Virasoro Lie algebras are inner.
