The inverse nodal problem on the smoothness of the potential function

Inverse Problems, 1999
The authors correct the lemma 2.2 in the paper by \textit{Y. H. Cheng}, \textit{C. K. Law} and \textit{J. Tsay} [J. Math. Anal. Appl. 248, 145--155 (2000; Zbl 0960.34018)]. Fortunately, the mistakes do not affect the validity of the results in the paper mentioned before.

INVERSE NODAL PROBLEM FOR THE INTEGRODIFFERENTIAL DIRAC OPERATOR WITH A DELAY IN THE KERNEL

Journal of Integral Equations and Applications, 2022
The author analyzes an inverse nodal problem for an integro-differential Dirac system with an integral delay on a finite interval. A uniqueness result is obtained for the solution of this problem, and a constructive procedure is proposed to solve it.

Inverse problems for the boundary value problem with the interior nodal subsets

Applicable Analysis, 2016
In this paper, inverse nodal problems for Sturm–Liouville equations with boundary conditions polynomially dependent on the spectral parameter were studied. The authors showed that some uniqueness theorems on the potential function hold by the Weyl function, respectively.

Inverse nodal problem for p–laplacian dirac system

Mathematical Methods in the Applied Sciences, 2016
In this study, we solve an inverse nodal problem for p‐Laplacian Dirac system with boundary conditions depending on spectral parameter. Asymptotic formulas of eigenvalues, nodal points and nodal lengths are obtained by using modified Prüfer substitution.

Inverse nodal problem for singular differential operators

Journal of Inverse and Ill-posed Problems, 2005
The inverse nodal problem is solved for the boundary value problem \[ -y''+\left(\frac{\nu-1/4}{x^2}+q(x)\right)y=\lambda y,\;\;\nu>0 ...

Inverse nodal problems for singular diffusion equation

Mathematical Methods in the Applied Sciences
In this study, some properties of the pencils of singular Sturm–Liouville operators are investigated. Firstly, the behaviors of eigenvalues and eigenfunctions is learned, then for each discontinuity point a solution of the inverse problem is given to determine the potential function and parameters , and with the help of a dense set of nodes.

Inverse nodal problem for polynomial pencil of Sturm‐Liouville operator

Mathematical Methods in the Applied Sciences, 2018
The paper is about boundary value problem for polynomial pencil of Sturm‐Liouville operators. Especially, we find all coefficients of the operator by using nodal points (zeros of eigenfunctions). Regularly, we find eigenvalues, nodal points, and nodal lengths by Prüfer substitution.
