摘要：

We prove that the integrated Krein's spectral shift function for one particle Schrodinger operators in R(3) is concave with respect to the perturbation potential. The proof is given by showing that the spectral shift function is the limit in the distributional sense of the difference of the counting functions for the given Hamiltonian and the free Hamiltonian in a finite domain Lambda with Dirichlet boundary conditions when Lambda --> infinity.
