In this article, we consider a discrete right-definite Sturm-Liouville problems with two squared eigenparameter-dependent boundary conditions. By constructing some new …
In this paper, inverse problems are studied for Sturm–Liouville difference operators having p 2− 1/4 m 2 type singularity. First, we define the Green's function and the corresponding Weyl …
