Number of eigenvalues for a class of non-selfadjoint Schrödinger operators
Xue Ping Wang
In this article, we prove the finiteness of the number of eigenvalues for a class of Schrödinger operators with a complex-valued potential on $\bR^n$, $n \ge…

Semiclassical analysis of a nonlinear eigenvalue problem and non analytic hypoellipticity
Bernard Helffer, Didier Robert, Xue Ping Wang
We give a semiclassical analysis of a nonlinear eigenvalue problem arising from the study of the failure of analytic hypoellipticity and obtain a general family of hypoelliptic, bu…

Smoothness and high energy asymptotics of the spectral shift function in many-body scattering
Andras Vasy, Xue-Ping Wang
Let H=Δ+\sum_{#a=2} V_a be a 3-body Hamiltonian, H_a the subsystem Hamiltonians, Δthe positive Laplacian of the Euclidean metric on X_0=R^n, V_a real-valued. Buslaev and Merkurev h…
