Poisson derivations and cohomology of Poisson nilpotent algebras
Stéphane Launois, Samuel Lopes, Isaac Oppong
We compute the Poisson derivations and the first Poisson cohomology group of uniparameter Poisson Nilpotent Algebras (PNA for short) under the hypothesis that Poisson-normal elemen…

Poisson derivations of a semiclassical limit of a family of quantum second Weyl algebras
S. Launois, I. Oppong
In previous paper, we studied deformations of the second Weyl algebra and computed their derivations. In the present paper, we identify the semiclassical limits $\mathcal…
