P, T, and PT−symmetries of impulsive Dirac systems

Abstract

This article is concerned with locations of bound states and spectral singularities of an impulsive Dirac system. By using a transfer matrix, we obtain some spectral properties of this impulsive system. We also examine some special cases, where the impulsive condition at the origin has P, T, and PT−symmetry. 

Keywords

• Impulsive operators
• bound states
