Spectra and fine Spectra of the upper triangular band matrix U(a;0;b) over the sequence space c0
Nuh Durna;Abstract
The aim of this paper is to obtain the spectrum, fine spectrum, approximate point spectrum, defect spectrum and compression spectrum of the operator U(a;0;b)on the sequence space $c_{0}$ where the non-zero diagonals are the entries of an oscillatory sequence.
