On the Lichnerowicz-Poisson cohomology complex and quasi-Poisson algebras

The article investigates F-commutative algebras with a Poisson structure from a non-Lie bivector Q, examines the resulting quasi-Poisson structure via the Lichnerowicz-Poisson coboundary, and focuses on constructing a Poisson subalgebra where δ2Q vanishes and on the existence of Poisson structures on specific Poisson ideals.
