Solving Barcilon's inverse problems by the method of spectral mappings
Journal of Differential EquationsIn 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 Barcilon's three spectra with the Weyl-Yurko matrix. Moreover, we prove the uniqueness theorem for the inverse problem solution by developing the ideas of the method of ...

Differential operators on graphs with a cycle [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2021 An inverse problem of spectral analysis is studied for Sturm – Liouville differential operators on a graph with a cycle. We pay the main attention to the most important nonlinear inverse problem of recovering coefficients of differential ...

Error Analysis for Mapped Legendre Spectral and Pseudospectral Methods [PDF]
SIAM Journal on Numerical Analysis, 2004 Mapping techniques are used for grid refinement in spectral methods to take localized features of the solution into account. The paper studies the influence of these mappings with respect to the approximation properties of the spectral discretization of partial differential equations.
