Reconstruction of the Sturm-Liouville differential operators with two constant delays

Miskolc Mathematical Notes
In this manuscript, we study the Sturm–Liouville differential operator with two constant delays. We investigate the properties of the asymptotic form of solutions, eigenvalues, and eigenfunctions of the operator. An inverse spectral problem is studied of

Transformation Operator for Sturm-Liouville Operators with Growing Potentials

Azerbaijan Journal of Mathematics
Summary: This paper considers a pair of Sturm-Liouville operators \(A=- \frac{d^2}{dx^2}+cx^{\alpha}\) and \(B=-\frac{d^2}{dx^2}+cx^{\alpha}+q(x)\) on the semi-axis \([0,\infty), c=const, \alpha \geq 1\). A transformation operator with a condition at infinity is constructed for the operators \(A\) and \(B\).
