On The Absolutely Continuous Spectrum Of Magnetic Schroedinger Operators

摘要

We prove that [0, ∞) is an essential support for the absolutely continuous part of the spectral measure associated with the magnetic Schroedinger operator (i▽ + A)~2 in L~2(R~v), given certain conditions on the decay of A. Bibliography: 8 titles. Illustrations: 1 figure.
