Stability of Inverse Resonance Problem on the Half Line
Lung-Hui Chen
We consider the inverse resonance problem in one-dimensional scattering theory. The scattering matrix consists of entries of meromorphic functions, which are quotients…

Uniqueness of Inverse Spectral Problem of Non-Local Sturm-Liouville Operators on Star Graph
Lung-Hui Chen
In this paper, we explore the inverse spectral problem of Sturm-Liouville operator on a star-like graph. To this fixed star-like graph centered at the origin as its vertex, we atta…

Recovering the Topology in One Point Interaction Problem on Extended Non-Local Star Graphs
Lung-Hui Chen
The author studies the inverse spectral problem of Sturm-Liouville operator on a star-like graph. To this star-like graph centered at the origin as its vertex, there are attached $…
