Splittable Lattices in the metabelian solvable Lie group
Béchir Dali, Moncef Riahi
The purpose of this note is describe and classify the splittable lattices in the completely solvable metabelian Lie group (semidirect product of abelian vector groups) $G:=\mathbb{…
Note on the cortex of two-step nilpotent Lie algebras
Bechir Dali
In this paper, we construct an example of a family of -dimensional two-step nilpotent Lie algebras so that the cortex of the dual of each is…
The spaces for some weight modules
Didier Arnal, Mabrouk Ben Ammar, Bechir Dali
We entirely compute the cohomology for a natural and large class of modules . We study the restriction to the cohomology of and appl…
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(-Modules of Symbols
Imed Basdouri, Mabrouk Ben Ammar, Béchir Dali +1
We consider the action of the Lie algebra of polynomial vector fields, , by the Lie derivative on the space of symbols $\mathcal{S}_δ^n=\bigoplus_{j=0}^n \mathc…
