Identification of Nonseparated Boundary Conditions

Abstract

We consider the problem of identification of nonseparated boundary conditions by five eigenvalues. Based on the Plücker conditions that appear in the problem of matrix recovery by its maximal-size minors, we construct the well-posedness set for this problem. We solve the problem of identification of the matrix of nonseparated boundary conditions in terms of the characteristic determinant of the corresponding spectral problem. The corresponding examples are presented.
