Singular perturbations of the dirac hamiltonian

open access: yes, 2017
This thesis is devoted to the study of the Dirac Hamiltonian perturbed by delta-type potentials andCoulomb-type potentials. We analysed on the delta-shell interaction on bounded and smooth domainsand its approximation by the coupling of the free Dirac operator with shrinking short rangepotentials.Under certain hypothesis of smallness of a regular ...
