Borg-type theorem for a class of fourth-order differential operators
Ai-Wei Guan, Chuan-Fu Yang, Natalia P. Bondarenko
In this paper, we study an inverse spectral problem for the fourth-order differential equation with real-valued coefficients and of $L^2(0,1)…
Sharp spectral transition for embedded eigenvalues of perturbed periodic Dirac operators
Kang Lyu, Chuanfu Yang
We consider the Dirac equation on \begin{align} Ly= \begin{pmatrix} 0&-1 1&0 \end{pmatrix} \begin{pmatrix} y_1 y_2 \end{pmatrix}'+ \begin{pm…
A class of higher order inverse spectral problems
Ai-Wei Guan, Chuan-Fu Yang, Natalia P. Bondarenko
In this paper, we consider the recovery of third-order differential operators from two spectra, as well as fourth-order or fifth-order differential operators from three spectra, wh…
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…
