Spectral representations for a class of banded Jacobi-type matrices
Abstract. 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.
Keywords: spectral representation, Laurent operators, Jacobi matrices.
