Note on the cortex of two-step nilpotent Lie algebras

Bechir Dali

In this paper, we construct an example of a family of $4 d$ -dimensional two-step nilpotent Lie algebras $(g_{d})_{d \geq 2}$ so that the cortex of the dual of each $g_{d}$ is…

Linear family of Lie brackets on the space of matrices $Mat(n\times m,\K)$ and Ado's Theorem

Bechir Dali

In this paper we classify a linear family of Lie brackets on the space of rectangular matrices $Mat(n\times m,\K)$ and we give an analogue of the Ado's Theorem. We give also a simi…

Deformation of Vect( $R)$ -Modules of Symbols

Imed Basdouri, Mabrouk Ben Ammar, Béchir Dali +1

We consider the action of the Lie algebra of polynomial vector fields, $vect (1)$ , by the Lie derivative on the space of symbols $\mathcal{S}_δ^n=\bigoplus_{j=0}^n \mathc…
