<p>Hallo,</p> <p>Let $(M,I,\omega)$ be a symplectic manifold. On this we can introduce a Poisson structure by $[A,B] = \omega(X_{A}, X_{B})$ where $X_{A}, X_{B}$ are defined by $\omega(X_{A}, *) = dA, \omega(X_{B}, *) = dB$ where $A,B$ are smooth functions on the manifold $M$. With respect to this structure there exists a foliation on $M$ by symplectic manifolds. Let assume here for simplicity that the foliation is regular and at least of codimension 2. My question is now: are the leaves of this foliation totally geodesic?if no, what assumptions needs one to make in order that the leaves are totally geodesic? I hope for a lot of answers. tanks in advance.</p> <p>Helge</p>
