Abstract :
The main purpose of this paper is to determine the ne spectrum of the generalized upper triangular
double-band matrices Δuv over the sequence spaces c0 and c. These results are more general than
the spectrum of upper triangular double-band matrices of Karakaya and Altun[V. Karakaya, M.
Altun, Fine spectra of upper triangular double-band matrices, Journal of Computational and Applied
Mathematics. 234(2010) 1387-1394].
