Poisson cohomology of SU(2)-covariant 'necklace' Poisson structures on S^{2}
Dmitry Roytenberg
We compute the Poisson cohomology of the one-parameter family of SU(2)-covariant Poisson structures on the homogeneous space S^{2}=CP^{1}=SU(2)/U(1), where SU(2) is endowed with it…

Quasi-Lie bialgebroids and twisted Poisson manifolds
Dmitry Roytenberg
We develop a theory of quasi-Lie bialgebroids using a homological approach. This notion is a generalization of quasi-Lie bialgebras, as well as twisted Poisson structures with a 3-…
