Finite inverse nodal problems for singular weighted Sturm--Liouville equations: variational selection and spectral matching

The recent work \cite{HeWuXiaZhang2025} introduced a finite-data inverse nodal framework for regular one-dimensional Sturm-Liouville operators. Nevertheless, formulating a multidimensional inverse nodal theory for Schr\"odinger operators remains a challenging open problem. This paper addresses this gap by establishing...
