Abstract This paper is devoted to studying a q-analog of the singular Dirac problem. First, we investigate some spectral properties of the problem. Then we prove the existence of a spectral function and establish a Parseval’s equality, for the sing

In this paper, linear second-order differential equations of Sturm-Liouville type having a finite number of singularities and turning points in a finite interval are investigated. First, we obtain the dual equations associated with the Sturm-Liouvill

A boundary value problem consisting of an integrodifferential equation, together with boundary conditions dependent on the spectral parameter, is investigated. The asymptotic behavior of the eigenvalues is studied, and we prove the uniqueness and the

In this paper, we formulate the boundary value problems for second-order differential equations having singular potentials of the form Ax−2 + f (x)x−1 + q0(x), where q0(x) ∈ Lloc(ω) and ω = (0, b). First, the existence and uniqueness theorems
