%0 Journal Article %T Deformations of coisotropic submanifolds for fibrewise entire Poisson structures %A Florian Schaetz %A Marco Zambon %J Mathematics %D 2012 %I arXiv %R 10.1007/s11005-013-0614-9 %X We show that deformations of a coisotropic submanifold inside a fibrewise entire Poisson manifold are controlled by the $L_\infty$-algebra introduced by Oh-Park (for symplectic manifolds) and Cattaneo-Felder. In the symplectic case, we recover results previously obtained by Oh-Park. Moreover we consider the extended deformation problem and prove its obstructedness. %U http://arxiv.org/abs/1207.1696v1
