Abstract:
Semiclassical asymptotics of the spectral shift function (SSF) for Schrödinger operator is studied at trapping energies. It is shown that the SSF converges to sum of a smooth function and a step function, which is essentially the counting function of resonances. In particular, the Weyl asymptotics is proved.
