-cohomology on multidifferential operators space
Didier Arnal, Mabrouk Ben Ammar
In this paper, we consider the known question of the computation of the cohomology spaces for the natural action of the Lie algebra acting on the space $\Dlm$ of…
Algèbres pré-Gerstenhaber à homotopie près
Walid Aloulou, Didier Arnal, Ridha Chatbouri
This paper is concerned by the concept of algebra up to homotopy for a structure defined by two operations and [,]. An important example of such a structure is the Gerstenhaber…
Cohomologie de Chevalley des graphes ascendants
Walid Aloulou, Didier Arnal, Ridha Chatbouri
The space of all tensor fields on , equipped with the Schouten bracket is a Lie algebra. The subspace of ascending tensors is a Lie subalgebra…
Le cône diamant symplectique
Didier Arnal, Olfa Khlifi
The diamond cone is a combinatorial description for a basis in a indecomposable module for the nilpotent factor n+ of a semi simple Lie algebra. After N.J. Wildberger who introduce…
Séparation des représentations par des surgroupes quadratiques
Didier Arnal, Mohamed Selmi, Amel Zergane
Let be an unitary irreducible representation of a Lie group . defines a moment set , subset of the dual of the Lie algebra of . Unfortunately, $I…
Algèbres et cogèbres de Gerstenhaber et cohomologie de Chevalley-Harrison
Walid Aloulou, Didier Arnal, Ridha Chatbouri
The fundamental example of Gerstenhaber algebra is the space of polyvector fields on , equipped with the wedge product and the Schouten brac…
