Index of $Γ$ -equivariant Toeplitz operators

Ryszard Nest, Florin Radulescu

Let $Γ$ be a discrete icc subgroup of PSL(2,R) of infinite covolume. and let M denote the quotient of the unit disc by $Γ$ . We prove that a Toeplitz operator with $Γ$ -invariant sym…

Deformations of symplectic Lie algebroids, deformations of holomorphic symplectic structures, and index theorems

Ryszard Nest, Boris Tsygan

Recently Kontsevich solved the classification problem for deformation quantizations of all Poisson structures on a manifold. In this paper we study those Poisson structures for whi…
