Explicit formulas for the Schroedinger wave operators in R^2 (1212.2230v1)
Published 10 Dec 2012 in math-ph, math.MP, and math.SP
Abstract: In this note, we derive explicit formulas for the Schroedinger wave operators in R2 under the assumption that 0-energy is neither an eigenvalue nor a resonance. These formulas justify the use of a recently introduced topological approach of scattering theory to obtain index theorems.
