Resumen:
We discuss the new representation of the Maslov canonical operator in the neighborhood of caustics and focal point working in some wide class of important physical problems. Using this representation we construct in particular asymptotic solution of the scattering problem for 2-D Dirac equation for graphene, the beam propagation in optics etc. This work was done together with V.Nazaikinskii, G.Makrakis and T.Tudorovskiy.
