Interaction Problems for n-Dimensional Dirac Operators with Singular Potentials

This paper is devoted to a brief review of the author’s recent results for n-dimensional Dirac operators with singular potentials, supported on smooth bounded and unbounded hypersurfaces and some new results on the reduction of problems of interaction for Dirac operators with singular potentials to integral equations on hypersurfaces of interaction, and the connection between the Fredholm property of interaction problems and the mentioned integral operators.
