Explicit formulas for the Schroedinger wave operators in R^2    [PDF]

S. Richard, R. Tiedra de Aldecoa

In this note, we derive explicit formulas for the Schroedinger wave operators in R^2 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.
