H. Boualem et al., LAGRANGIAN FIBRATION ENDOWED WITH A COMPATIBLE PSEUDO-METRIC, Comptes rendus de l'Academie des sciences. Serie 1, Mathematique, 326(10), 1998, pp. 1201-1204
We study a kind of Lagrangian fibrations whose total space is endowed
with a compatible pseudo-metric. Under suitable geometrical conditions
we construct, on the basis, a family of invariants which classify, th
