On The Fine Spectrum of Generalized Upper Triangular Triple-Band Matrices (Delta(uvw)2)(t) Over the Sequence Space l(1)

Abstract

In this work, we determine the fine spectrum of the matrix operator (Delta(2)(uvw))(t) which is defined generalized upper triangular triple band matrix on l(1). Also, we give the approximate point spectrum, defect spectrum and compression spectrum of the matrix operator (Delta(2)(uvw))(t) on l(1).
