On The Fine Spectrum of Generalized Lower Triangular Double Band Matrices Over The Sequence Space
Abstract. The generalized difference operator has been defined by Fathi and Lashkaripour: with , are convergent sequences of nonzero real numbers satisfying certain conditions. The purpose of this paper is to completely determine the approximate point spectrum, the defect spectrum and the comprossion spectrum of the operator on the sequence …
