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…

Relative Perturbation Bounds for the Joint Spectrum of Commuting Tuple of Matrices

Arnab Patra, P. D. Srivstava

In this paper, we study the relative perturbation bounds for joint eigenvalues of commuting tuples of normal $n \times n$ matrices. Some Hoffman-Wielandt type relative perturbation…
