本文考虑一类Sturm-Liouville问题的谱逆问题,该问题由定义在区间[0,a]上的Sturm-Liouville方程和端点0和a处的两个分离的边界条件组成,其中一个边界条件涉及函数f(λ).当f(λ)是Herglotz函数型且已知为先验时,我们证明了[0,a]上的势和另一边界条件可以根据谱上的适当部分信息和正规化常数集上的部分信息唯一确定.
The inverse spectral problem for a Sturm–Liouville problem which consists of a Sturm–Liouville equation defined on the interval [0, a] and two separated boundary conditions at the endpoints 0 and a, one of which is involved function f (λ), is considered in this paper. When f (λ) is the type of Herglotz functions and is known as a priori, we prove that the potential on [0, a] and the other boundary condition can be uniquely determined in terms of appropriate partial information on the spectrum and partial information on the set of normalizing constants.
