Spectral and scattering theory for symbolic potentials of order zero
Andrew Hassell, Richard B. Melrose, András Vasy
The spectral and scattering theory is investigated for a generalization, to scattering metrics on two-dimensional compact manifolds with boundary, of the class of smooth potentials…

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…
