On a non-self-adjoint Sturm–Liouville problem: spectral and inverse analysis
Abstract In this paper, we study a Sturm–Liouville boundary value problem with a complex-valued potential represented by an absolutely convergent Fourier series. We construct fundamental solutions, define the characteristic function, and analyze the discrete spectrum. By extending the potential to t...
