摘要
奇型Sturm-Liouville问题的势函数q(x)由两组谱唯一确定的,Sturm-Liouville算子的半逆问题讨论由一组谱和一半势函数唯一确定势函数q(x).本文利用Koyunbakan和Panakhov的方法,证明一组谱和(π/2,π)上的势函数q(x)唯一确定(0,π)上Sturm-Liouville方程含有奇型的1sin2x的势函数q(x).
The potential q(x) of singular Sturm-Liouville operators can be uniquely determined from two spectrum, Half-inverse problem for Sturm-Liouville operators consists of reconstruction of this operator by its spectrum and half of the potential. In this paper, using Koyunbakn and Panakhov's method, we show that if q(x) is prescribed on 0 (π/2,π), then only one spectrum is sufficient to determine q(x) on the interval (0, π) for the Sturm-Liouville equation having singularity type 1/sin2x on (0,π).
