    Spectral representations for a class of banded Jacobi-type matrices
    (2014) Zalot, Ewelina; Majdak, Witold
    We describe some spectral representations for a class of non-self-adjoint banded Jacobi-type matrices. Our results extend those obtained by P.B. Naïman for (two-sided infinite) periodic tridiagonal Jacobi matrices.

    Spectral resolutions for non-self-adjoint block convolution operators
    (Wydawnictwa AGH, 2022) Zalot, Ewelina
    The paper concerns the spectral theory for a class of non-self-adjoint block convolution operators. We mainly discuss the spectral representations of such operators. It is considered the general case of operators defined on Banach spaces. The main results are applied to periodic Jacobi matrices.
