Abstract:

Let \(\) be the two dimensional Schrödinger operator with the real valued potential V which satisfies the decay condition at infinity \(\) for \(\). We show that the wave operators \(\), \(\), are bounded in \(\) for any 1<p<∞ under the condition that H has no zero bound states or zero resonance, extending the corresponding results for higher dimensions. As W± intertwine H0 and the absolutely continuous part H Pac of H : f(H)Pac=W±f(H0 )W±* for any Borel function f on ℝ1, this reduces the various Lp-mapping properties of f(H)Pac to those of f(H)0), the convolution operator by the Fourier transform of the function f2).
