| Abstract: | We study the semi-classical behavior of the spectral function of the Schrödinger operator with short range potential. We prove that the spectral function is a semi-classical Fourier integral operator quantizing the forward and backward Hamiltonian flow relations of the system. Under a certain geometric condition we explicitly compute the phase in an oscillatory integral representation of the spectral function. |
| Keywords: | Semi-classical Schr" {o}dinger operators, spectral function, Fourier integral operators. |
