Nebojša Djurić, Biljana Vojvodić

AI总结:

本文研究时滞小于区间长度三分之一的Dirac型算子逆谱问题,证明两个谱不足以完全恢复势函数,并讨论了Ambarzumian型逆问题。

摘要:

本文研究带常时滞的Dirac型算子的逆谱问题,特别是当时滞小于区间长度的三分之一时。研究聚焦于特征值行为以及从谱中恢复算子的问题。我们发现仅凭两个谱不足以完全恢复势函数。此外,我们考虑了带时滞的Dirac型算子的Ambarzumian型逆问题。我们的结果对常时滞微分算子相关逆问题的研究具有重要意义,并可为该领域未来的研究方向提供参考。

英文摘要:

This paper addresses inverse spectral problems associated with Dirac-type operators with a constant delay, specifically when this delay is less than one-third of the interval length. Our research focuses on eigenvalue behavior and operator recovery from spectra. We find that two spectra alone are insufficient to fully recover the potentials. Additionally, we consider the Ambarzumian-type inverse problem for Dirac-type operators with a delay. Our results have significant implications for the study of inverse problems related to the differential operators with a constant delay and may inform future research directions in this field.
