Inverse nodal problems on quantum tree graphs

Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 2021
We consider inverse nodal problems for the Sturm–Liouville operators on the tree graphs. Can only dense nodes distinguish the tree graphs? In this paper it is shown that the data of dense-nodes uniquely determines the potential (up to a constant) on the tree graphs. This provides interesting results for an open question implied in the paper.

Solution of inverse nodal problems

Inverse Problems, 1989
We show that the coefficients in a second-order differential equation can be determined from the positions of the nodes for the eigenfunctions. We prove uniqueness results, derive approximate solutions, give error bounds and present numerical experiments.

Inverse nodal problems for singular problems in the half-line

Boletín de la Sociedad Matemática Mexicana, 2023
In this paper, an inverse problem for a singular ordinary differential equation in the half-line is considered. The authors consider a class of positive weights \(\sigma\in L^{1}([0,\infty])\) with \(\int_{0}^{\infty}t\sigma(t ...

Approximate solutions of inverse nodal problem with conformable derivative

2023
Summary: Our research is about the Sturm-Liouville equation which contains conformable fractional derivatives of order \(\alpha \in (0,1]\) in lieu of the ordinary derivatives. First, we present the eigenvalues, eigenfunctions, and nodal points, and the properties of nodal points are used for the reconstruction of an integral equation.
