Special Kahler geometry of classical integrable systems
The main purpose of the talk is to describe the hyper-symplectic structure
which is associated to every (real) lagrangian fibration over a symplectic
manifold, whose symplectic form is covariantly constant.
On the base of such a fibration a special Kahler structure is naturally
defined.
Possible applications of this geometric setting to the theory of classical
integrable systems of will be suggested.
