A spectral shift function for Schrödinger operators with singular interactions
Jussi Behrndt, Fritz Gesztesy, Shu Nakamura
For the pair of self-adjoint Schrödinger operators in a spectral shift function is determined in an explicit form with the help of (…

Spectral shift functions and Dirichlet-to-Neumann maps
Jussi Behrndt, Fritz Gesztesy, Shu Nakamura
The spectral shift function of a pair of self-adjoint operators is expressed via an abstract operator valued Titchmarsh--Weyl -function. This general result is applied to differ…

The spectrum of the scattering matrix near resonant energies in the semiclassical limit
Shu Nakamura, Alexander Pushnitski
The object of study in this paper is the on-shell scattering matrix of the Schrödinger operator with the potential satisfying assumptions typical in the theory of shape reso…
