| Abstract: | The relation between a “nonrelativistic” Hamiltonian of the formH ∞=(A+B)2+C and a corresponding family of “Dirac-Hamiltonians”H(c) in the limitc → ∞ is investigated. It is shown that the resolvent (z ?H(c))?1 and the relativistic perturbation of isolated eigenvalues ofH ∞ are analytic in 1/c for sufficiently large |c|. |
