Titchmarsh-Weyl theory and Levinson's theorem for Dirac operators
Description
For a Dirac system with a perturbation potential V(r) obeying integral 0∞(1+r) mod dr<∞, the behaviour of the Titchmarsh-Weyl m-function near the spectral-gap endpoints is examined. As a consequence, we obtain another demonstration of the Levinson theorem (1949). (author)
