| Research Abstract |
In the first year (Heisei 13), as a first step of studying of Poissonization of Nambu-Jacobi structures, we handled tangent distributions whose co-rank are no less than 2 and studies about relations between their annihilator sub-bundles and geometric properties of them. When co-dimension is 2, the dimension of manifold should be even and we checked that Engel manifolds are one of those examples. On the other hand, it turned out any 2-dimensional non-involutive distribution has this property and higher dimensional cases are still left unsolved for us.
In the second year (Heisei 14), we have payed attention to tangent distributions generated by 2-vector field. We found a Lie algebroid which looks brand-new. We asked A. Weinstein (Univ. of California, Berkeley) and I. Vaisman (Univ. of Haifa) about our result and got reply that they think our result is new and original. We are writing this research as a tentative title "Integrability of plane fields defined by 2-vector fields" as a joint-work with Professor T. Mizutani at Saitama Univ.
