Abstract
The fine spectra of lower triangular double-band matrices have been examined by several authors (e.g. [13,22]). Here we determine the fine spectra of upper triangular double-band matrices over the sequence spaces c 0 and c . Upper triangular double-band matrices are infinite matrices which include the left-shift, averaging and difference operators.
