Abstract

In the present paper, we extend the main results of Jeribi in [6] to weighted and pseudo-weighted spectra of operators in a nonseparable Hilbert space ${\mathcal{H}}$ . We investigate the characterization, the stability and some properties of these weighted and pseudo-weighted spectra.

Keywords

Fredholm operators; ${\alpha}-Fredholm$ operator; pseudo-spectrum; weighted spectrum;
