On the spectrum and fine spectrum of an upper triangular double-band matrix on sequence spaces abstract
In this paper, we investigate the spectrum and fine spectrum of the upper triangular double-band matrix \Delta ^{uv} on cs sequence space. We also determine the approximate point spectrum, the defect spectrum and the compression spectrum of this matrix on cs.
