Spectrum and fine spectrum of generalised lower triangular triple band matrices over the sequence space $l_{p}$

Arnab Patra, P. D. Srivastava

The spectrum of triangular band matrices defined on the sequence spaces where the entries of each band is a constant or convergent sequence is well studied. In this article, the sp…

On some study of the fine spectra of generalized difference operator $Δ_{a, b}$ on $ℓ_{p} (1 < p < \infty)$

Riddhick Birbonshi, Arnab Patra, P. D. Srivastava

In this paper, we determine the spectrum, the point spectrum, the continuous spectrum and the residual spectrum of the generalized difference operator $Δ_{a, b}$ on the sequence spa…

Spectra of the lower triangular matrix $B (r_{1}, \dots, r_{l}; s_{1}, \dots, s_{l^{'}})$ over $c_{0}$

Sanjay Kumar Mahto, Arnab Patra, P. D. Srivastava

The spectra and fine spectra of the lower triangular matrix $B$ $(r_{1}, \dots, r_{l};$ $s_{1}, \dots, s_{l^{'}})$ over the sequence space $c_{0}$ are determined. The diagonal and s…
