Determination of a differential pencil from interior spectral data on a union of two closed intervals
(09/02/2022)
In this paper, we consider a quadratic pencil of Sturm–Liouville operator on closed sets. We study an interior-inverse problem for this kind operator and give a uniqueness theorem with an appropriate example.
Spectral Problems for Sturm–Liouville Operator with Eigenparameter Boundary Conditions on Time Scales
(09/09/2022)
In this paper, we consider the inverse problem for Sturm-Liouville operators with eigenparameter dependent boundary conditions on time scales. We give new uniqueness theorems and investigate its some special cases.
