Poisson (co)homology of truncated polynomial algebras in two variables
Stephane Launois, Lionel Richard
We study the Poisson (co)homology of the algebra of truncated polynomials in two variables viewed as the semi-classical limit of a quantum complete intersection studied by Bergh an…

On Morita equivalence for simple Generalized Weyl algebras
Lionel Richard, Andrea Solotar
We give a necessary condition for Morita equivalence of simple Generalized Weyl algebras of classical type. We propose a reformulation of Hodges' result, which describes Morita equ…

Twisted Poincare duality for some quadratic Poisson algebras
S. Launois, L. Richard
We exhibit a Poisson module restoring a twisted Poincare duality between Poisson homology and cohomology for the polynomial algebra R=C[X_1,...,X_n] endowed with Poisson bracket ar…
