Differential operators on supercircle: conformally equivariant quantization and symbol calculus
Hichem Gargoubi, Najla Mellouli, Valentin Ovsienko
We consider the supercircle equipped with the standard contact structure. The conformal Lie superalgebra K(1) acts on as the Lie superalgebra of contact vector…

Large Coadjoint representation of Virasoro-type Lie algebras and differential operators on tensor-densities
Valentin Ovsienko
We discuss the geometrical nature of the coadjoint representation of the Virasoro algebra and some of its generalizations. The isomorphism of the coadjoint representation of the Vi…
