Abstract:
We develop scattering theory for the Laplace operator in the half-space
with Robin type boundary conditions on the boundary plane. In particular,
we show that, in addition to usual space waves living
in cones and described by standard wave operators, surface waves may arise
in this problem. They are localized in parabolic neighbourhoods of the boundary.
We find conditions on the boundary coefficient ensuring the existence
of surface waves. Several open problems are formulated.
Keywords:
Schrödinger equation, asymptotics at infinity, surface waves.
