An Example of Rank 2 Poisson Structure which is Stable Under Deformations

Abstract

Let $\Pi$ be a rank $2$ Poisson Structure in the Projective Space defined by the dimension $2$ foliation $\mathcal{F}$ in the pull-back component. We prove that for a generic choice of $\mathcal{F}$, the irreducible component of the Poisson structures containing $\Pi$ and the irreducible component of Foliations containing $\mathcal{F}$ coincides.
