Around the classical string problem,ns that minimize certain weighted averages of the density. There exists a simple set of necessary conditions of these weights. In particular, it has been shown that the only weight functions f(x)than can be consistent in all cases with the existence of an extremal density which is made up of a finit

A geometrical approach to the nonlinear solvable equations,led “symplectic Kahler manifolds”, is suggested. This approach is constructive, tensorial and simple in its ideas. It allows to recover the equations obtained through the socalled AKNS approach, together with some other examples. It leads to conjecture a possible “integrability condition” for infini
