| Özet |
| The spectral analysis of a non-selfadjoint Sturm-Liouville equation (SLE) with continuous and discrete spectrum was investigated by Naimark [13]. He proved the existence of the spectral singularities in the continuous spectrum of SLE. Lyance showed that the spectral singularities play an important role in the spectral theory of SLE [12]. He also studied the effect of the spectral singularities in the spectral expansion of SLE in terms of the principal functions. Some problems of the spectral analysis of a non-selfadjoint Schrödinger, Dirac and Klein-Gordon differential and difference equations with spectral singularities were studied in [1],[4],[5],[7]−[10]. Let us consider the boundary value problem (BVP)− y+[V (x)+ 2λU (x)− λ2] y= 0, x∈ R+=[0,∞),(1.1) y (0)= 0,(1.2) |
