INVERSE NODAL PROBLEM FOR THE STURM-LIOUVILLE OPERATOR WITH THREE DISCONTINUITIES
INVERSE NODAL PROBLEM FOR THE STURM-LIOUVILLE OPERATOR WITH THREE DISCONTINUITIES
摘要
In this work,the inverse nodal problem for the Sturm-Liouville operator with three dis-continuities is studied.It is proved that the dense nodes of the eigenfunctions can uniquely determine the potential on the whole interval and some parameters,and a reconstruction algorithm for the solution is presented.Finally,numerical examples were provided,and the effectiveness of the algorithm was verified through numerical calculations.
