$δ$ -biderivations of Virasoro related algebras

Chengkang Xu

We determine all $δ$ -biderivations for the Witt algebra, the Virasoro algebra, the $W$ -algebras $W (a, b)$ and their universal central extensions $W (a, b)$ , and then give s…

Automorphisms, derivations and central extensions of Lie algebras arising from quantum tori

Chengkang Xu

For a Lie algebra $g$ related to a quantum torus, we compute its automorphisms, derivations and universal central extension. This Lie algebra $g$ is isomorphic…

Deformed higher rank Heisenberg-Virasoro algebras

Chengkang Xu

In this paper, we study a class of infinitesimal deformations of the centerless higher rank Heisenberg-Virasoro algebras. Explicitly, the universal central extensions, derivations…
