Differential Operators on the Weighted Densities on the Supercircle $S^{1∣ n}$

Nader Belghith, Mabrouk Ben Ammar, Nizar Ben Fraj

Over the $(1, n)$ -dimensional real supercircle, we consider the $K (n)$ -modules of linear differential operators, $D_{λ, μ}^{n}$ , acting on the superspaces of weighted…

The Binary Invariant Differential Operators on Weighted Densities on the superspace $R^{1∣ n}$ and Cohomology

Mabrouk Ben Ammar, Nizar Ben Fraj, Salem Omri

Over the $(1, n)$ -dimensional real superspace, $n > 1$ , we classify $K (n)$ -invariant binary differential operators acting on the superspaces of weighted densities, where $\m…

Deformations of modules of differential forms

B. Agrebaoui, M. Ben Ammar, N. Ben Fraj +1

We study non-trivial deformations of the natural action of the Lie algebra $Vect (R^{n})$ on the space of differential forms on $R^{n}$ . We calculate abstra…
