| Abstract: | The fine spectra of triangular double-band and triple-band matrices were examined by several authors. Here we determine the fine spectra of Toeplitz operators, which are represented by upper and lower triangular n-band infinite matrices, over the sequence spaces c0 and c. Also some spectral results over ?∞ are given. |
