On the eigenvalues of operators with gaps. Application to Dirac operators II.
ABSTRACT. This paper is an improved version of mp-arc 99-199. In the present version,
we introduce a new abstract continuation principle. With this principle, the
study of the Dirac operator with Coulomb-like potential is greatly simplified
and additional results are easily obtained.
