The confoliation programme
In dimension 3 it is known, due to Eliashberg-Thurston, that any foliation can be C0-approximated by a positive and a negative contact structure. Is the same true in higher dimensions for a symplectic foliation?
(A. Mori) In higher dimensions one can provide an alternate definition of confoliation: We say that a pair (\alpha,\tau) is a twisted contact structure, with \alpha a 1-form and \tau a 2-form, if d\alpha+\tau is non-degenerate along ker(alpha). Then, we will say that \alpha is a confoliation if there is a linear family \tau_x, x in (0,1], with (\alpha,\tau_x) twisted contact. In particular, this implies that αΛ(dα)^n is non-negative. One particular example of such a confoliation is the symplectic foliation considered by Mitsumatsu in S5.
