Monge-Ampère Equations, Their Invariants and (Generalised) Geometries

The Monge-Ampère (MAE) equations are important 2nd order non-linear
equations which appear in many domains of mathematics and
mathematical physics --- from differential geometry of surfaces to so-called
non-compact Calabi-Yau varieties and "non-cosmic" strings, problems of
optimal mass transportation and the Mirror Conjecture.

In my talk I shall try to explain a geometric approach to this class of
equations, which is based on some ideas and methods from contact and
symplectic geometry. This approach leads not only to a possibility to
solve (sometimes :) ) the MAE exactly, to find their symmetries and conservation laws
but also provides a study of some interesting (classical and generalised)
geometric structures.
