With respect to the spectral properties of L, we investigate the properties of the principal functions corresponding to the eigenvalues and the spectral singularities of L, if (Formula Presented.) holds for some ε> 0 and δ∈[12,1].falsediscrete Dirac equation | eigenvalue | principal function | spectral analysisArticle10.1007/s10474-016-0638-610.1007/s10474-016-0638-62-s2.0-84978708657WOS:0003874711000053243381501588-2632
