Real normalized differentials and their applications

Résumé :
A general notion of real normalized differentials has arisen in the spectral theory of two dimensional quasiperiodic operators. They are central for the Whitham perturbation theory of soliton equation. In the talk I present their applications to the study of geometry of moduli spaces of curves with puncture and generalization of notions of amoebas and Ronkin function for quasiperiodic difference operators.
