On the third cohomology of the Lie algebra of vector fields on weighted densities on R
Wajd Afsi, Salem Omri
Let Vect() be the Lie algebra of smooth vector fields on and be the space of -densities on . Vect() acts on $\mat…
The Binary -Invariant Differential Operators On Weighted Densities On The Superspace And -Relative Cohomology
Khaled Basdouri, Salem Omri, Wissal Swilah
We consider the module structure on the spaces of differential bilinear operators acting on the superspaces of weighted densities. We classify $\mathfrak{aff}…
The Binary Invariant Differential Operators on Weighted Densities on the superspace and Cohomology
Mabrouk Ben Ammar, Nizar Ben Fraj, Salem Omri
Over the -dimensional real superspace, , we classify -invariant binary differential operators acting on the superspaces of weighted densities, where $\m…
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…
Deforming the Lie Superalgebra of Contact Vector Fields on
Boujemaa Agrebaoui, Nizar Ben Fraj, Salem Omri
We classify nontrivial deformations of the standard embedding of the Lie superalgebra K(1) of contact vector fields on the (1,1)-dimensional supercircle into the Lie superalgebra o…
