Derivations and automorphism groups of the original deformative Schrödinger-Virasoro algebras

Abstract

In this paper, we determine the derivation algebra and the automorphism group of the original deformative $\mathrm{Schr}\ddot{\mathrm{o}}\mathrm{dinger}$-{\rm Virasoro} algebras which is the semi-direct product Lie algebra of the Witt algebra and its tensor density module ${\mathrm{I}}^{\mathrm{g}}(a,b)$.
