On a general approach to the formal cohomology of quadratic Poisson structures
Mohsen Masmoudi, Norbert Poncin
Abstract
We propose a general approach to the formal Poisson cohomology of r-matrix induced quadratic structures, we apply this device to compute the cohomology of structure 2 of the Dufour-Haraki classification, and provide complete results also for the cohomology of structure 7.
