Spectral and scattering theory for symmetric systems of nonconstant deficit
The author studies spectral and scattering problems for first order symmetric systems of non-constant deficit. A major portion of the paper is devoted to discreteness of eigenvalues, absolute continuity of the continuous spectrum, and the principle of limiting absorption.
