Abstract:
We suggest a new representation of Maslov's canonical operator in a neighborhood of caustics using a special class of coordinate systems (eikonal coordinates) on Lagrangian manifolds. We present the results in the two-dimensional case and illustrate them with examples.
Keywords:
semiclassical asymptotics, focal point, caustic, integral representation, Bessel function, Schrödinger equation, wave beam.
