Les pré-(a,b)-algèbres à homotopie près
Walid Aloulou
We study in this article the concept of algebra up to homotopy for a structure defined by two operations . Important examples of such structure are those of pre-Gerstenhaber and pr…
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…
Les (a,b)-algèbres à homotopie près
Walid Aloulou
We study in this article the concepts of algebra up to homotopy for a structure defined by two operations $ \pt $ and . Having determined the structure of algebr…
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…
Cohomologie de Chevalley des graphes vectoriels
Walid Aloulou, Didier Arnal, Ridha Chatbouri
The space of smotth functions and vector fields on is a Lie subalgebra of the (graded) Lie algebra , equipped with the Scouten bracket. In this paper, we co…
