Spectrum and fine spectrum of the upper triangular matrix U(r, s) over the sequence spaces
Fine spectra of various matrix operators on different sequence spaces have been investigated by several authors. Recently, some authors have determined the approximate point spectrum, the defect spectrum and the compression spectrum of various matrix operators on different sequence spaces. Here in t...
