On the spectrum of the tridiagonal matrices with two-periodic main diagonal
Alexander Dyachenko, Mikhail Tyaglov
We find the spectrum and eigenvectors of an arbitrary irreducible complex tridiagonal matrix with two-periodic main diagonal provided that the spectrum and eigenvectors of the matr…

Direct and inverse spectral problems for a class of non-selfadjoint band matrices
Natalia Bebiano, Mikhail Tyaglov
The spectral properties of a class of band matrices are investigated. The reconstruction of matrices of this special class from given spectral data is also studied. Necessary and s…

On the spectra of Schwarz matrices with certain sign patterns
Mikhail Tyaglov
The direct and inverse spectral problems are solved for a wide subclass of the class of Schwarz matrices. A connection between the Schwarz matrices and the so-called generalized Hu…
