-  * (R.L. Fernandes, F. Presas, G. Meigniez) Conjecture: Let M be a closed, odd-dimensional, simply--connected manifold. Then it does not admit a codimension-1 strong symplectic foliation. It is known by work of Mitsumatsu that the 5-sphere does admit a weak symplectic foliation. In dimension 3, the conjecture is true due to Novikov's theorem.+  * **(R.L. Fernandes, F. Presas, G.

-  * (A. Mori) Related conjecture: Let (M,F) be aa codimension-1 oriented foliation on a closed odd dimensional manifold. If the space of leafwise closed non-degenerate 2-forms is non-empty and contains no closed forms, there exists a closed leaf.+  * **(A.
