Deformations of Symmetric Simple Modular Lie (Super)Algebras
Sofiane Bouarroudj, Pavel Grozman, Dimitry Leites
We say that a Lie (super)algebra is ''symmetric'' if with every root (with respect to the maximal torus) it has the opposite root of the same multiplicity. Over algebraically close…

The ternary invariant differential operators acting on the spaces of weighted densities
Sofiane Bouarroudj
Over n-dimensional manifolds, I classify ternary differential operators acting on the spaces of weighted densities and invariant with respect to the Lie algebra of vector fields. F…
