[HTML][HTML] Rigidity of Hamiltonian actions on Poisson manifolds
This paper is about the rigidity of compact group actions in the Poisson context. The main
result is that Hamiltonian actions of compact semisimple type are rigid. We prove it via a …

Picard groups of Poisson manifolds
H Bursztyn, RL Fernandes - Journal of Differential Geometry, 2018 - projecteuclid.org
For a Poisson manifold $ M $ we develop systematic methods to compute its Picard group
$\mathrm {Pic}(M) $, ie, its group of self Morita equivalences. We establish a precise …

Contact isotropic realisations of Jacobi manifolds
MA Salazar, D Sepe - 2014 - recercat.cat
This paper investigates the local and global theory of contact isotropic realisations of Jacobi
manifolds, which are contact realisations of minimal dimension. These arise in the study of …
