  • On the Eigenvalues of a Norlund Infinite Matrix as an Operator on Some Sequence Spaces 
    Wali, Augustus N.; Ochieng, Godrick F.; Akanga, Jotham R. (GLOBEEDU Group, 2016-08)
    In various papers some authors have previously investigated [1], [2], [3], [4], [5] and determined the spectrum of weighted mean matrices considered as bounded operators on various sequence spaces. In this study, we determine ...
  • On the spectrum of a special Nörlund matrix as an operator on c0 
    Okello, I. A.; Akanga, J. R .; Wali, Augustus N. (2017)
    In summability theory, different classes of matrices have been investigated and characterized. There are various types of summability methods e.g. Nörlund means, Cesaro, Riesz, Euler, Abel and many others. The spectrum ...
