摘要
In this work, we study the inverse problem for the Sturm-Liouville operator -D(2) + q with discontinuity boundary conditions inside a finite closed interval. Using spectral data of a kind, it is shown that the potential function q(x) can be uniquely determined by a set of values of eigenfunctions at some internal point and one spectrum.
