===== 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?

  *  In dimension 3 tautness of the foliation implies tightness of the contact structure. In higher dimensions, being strong symplectic implies that any approximation (if it exists) is fillable and thus tight as well.

  *  **(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.
