• Central extension
• Derivation algebra
• Witt algebra

In this article, we determine one-dimensional (Leibniz) central extensions, the derivation algebra, and the automorphism group of the infinite-dimensional Lie algebra W(a, b) (for a, b is an element of C) which is the semidirect product Lie algebra of the Witt algebra and its tensor density module I(a, b).
