On the third cohomology of the Lie algebra of vector fields on weighted densities on R

Wajd Afsi, Salem Omri

Let Vect( $R$ ) be the Lie algebra of smooth vector fields on $R$ and $F_{λ}$ be the space of $λ$ -densities on $R$ . Vect( $R$ ) acts on $\mat…

The Binary $aff (n ∣1)$ -Invariant Differential Operators On Weighted Densities On The Superspace $R^{1∣ n}$ And $aff (n ∣1)$ -Relative Cohomology

Khaled Basdouri, Salem Omri, Wissal Swilah

We consider the $aff (n ∣1) -$ module structure on the spaces of differential bilinear operators acting on the superspaces of weighted densities. We classify $\mathfrak{aff}…

Deforming the Lie Superalgebra of Contact Vector Fields on $S^{1∣1}$

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…
