Study of formality for the Heisenberg algebra

Olivier Elchinger

In this paper, we compute the Chevalley-Eilenberg cohomology of the three-dimensionnal Heisenberg Lie algebra with values in its universal enveloping algebra. We also compte the Sc…

Brackets with $(τ, σ)$ -derivations and $(p, q)$ -deformations of Witt and Virasoro algebras

Olivier Elchinger, Karl Lundengard, Abdenacer Makhlouf +1

The aim of this paper is to study some brackets defined on $(τ, σ)$ -derivations satisfying quasi-Lie identities. Moreover, we provide examples of $(p, q)$ -deformations of Witt and Vi…
