This paper deals with a discontinuous Dirac operator with an eigenparameter in the boundary condition. By using Lidskii's theorem, we investigate the completeness of the system of eigenfunctions of such an operator. 2010 Mathematics Subject Classification. Primary 34L10, 34L40. Keywords. Dissipative Dirac operator, eigenparameter in the boundary condition, completeness of the system of eigenvectors and associated vectors, Lidskii's theorem.
