| Abstract | Fine spectra of various matrix operators on different sequence spaces have been examined by several authors. Recently,some authors have determined the approximate point spectrum, the defect spectrum and the compression spectrum of variousmatrix operators on different sequence spaces. Here in this article we have determined the spectrum and fine spectrum of thelower triangular matrix B r s t ? , , ? on the sequence space cs. In a further development, we have also determined the approximatepoint spectrum, the defect spectrum and the compression spectrum of the operator B r s t ? , , ? on the sequence space cs. |
