|b The fine structure of spectra of many operators, which are represented by matrices, remain to be studied. For example, the fine structure of the spectrum of the upper and lower triangular double-band matrices have been studied in some special cases. The main target of this work is to study the spectrum and fine spectrum of the operator Δ ab on the sequence spaces c and c0. Three methods for classifying the spectrum are considered. Further, some illustrative examples are provided to support our new results.
