Ambarzumyan-type theorem for vectorial Sturm-Liouville operator with impulses

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Chuan-Fu Yang | Summary: We consider the vector-impulsive Sturm-Liouville problem with Neumann conditions. The Ambarzumyan$^{textbf{,}}$s theorem for the problem is proved, which states that if the eigenvalues of the problem coincide with those of the zero potential, then the potential is zero. | Search Query: […]

Incomplete inverse problem for Dirac operator with constant delay

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Chuan-Fu Yang | Summary: In this work, we consider Dirac-type operators with a constant delay less than two-fifths of the interval and not less than one-third of the interval. For our considered Dirac-type operators, an incomplete inverse spectral problem is studied. Specifically, when two complex […]
