Finite energy subspace for time-periodic Schrödinger operators
Erik Skibsted
For -body Schrö\-dinger operators with time-periodic short-range pair-potentials we show by a time-dependent commutator method that all channel wave operators exist. For w…

Asymptotic completeness for short-range N-body systems revisited
Erik Skibsted
We review Yafaev's approach to asymptotic completeness for systems of particles mutually interacting with short-range potentials. The theory is based on computation of commutators…
