Ambarzumyan-type theorem for the Sturm-Liouville operator on the lasso graph
Feng Wang, Chuan-Fu Yang
We consider the Sturm-Liouville operator on the lasso graph with a segment and a loop joined at one point, which has arbitrary length. The Ambarzumyan's theorem for the operator is…
Inverse problems for Dirac operators with a constant delay less than half of the interval
Feng Wang, Chuan-Fu Yang
In this work, we consider Dirac-type operators with a constant delay less than half of the interval and not less than two-fifths of the interval. For our considered Dirac-type oper…
Ambarzumyan-type theorem for vectorial Sturm-Liouville operator with impulses
Feng Wang, Chuan-Fu Yang
We consider the vector-impulsive Sturm-Liouville problem with Neumann conditions. The Ambarzumyans theorem for the problem is proved, which states that if the eigenv…
Incomplete inverse problem for Dirac operator with constant delay
Feng Wang, Chuan-Fu Yang
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…
Solving Barcilon's inverse problems by the method of spectral mappings
Aiwei Guan, Chuanfu Yang, Natalia P. Bondarenko
In this paper, we consider Barcilon's inverse problem, which consists of the recovery of the fourth-order differential operator from three spectra. We obtain the relationship of Ba…
