Abstract
There are many different ways to subdivide the spectrum of a
bounded linear operator; some of them are motivated by
applications to physics (in particular, quantum mechanics). In a
series of papers, B.E. Rhoades and M. Yildirim previously
investigated the spectra and fine spectra for factorable matrices,
considered as bounded operators over various sequence spaces. In
the present paper, approximation point spectrum, defect spectrum
and compression spectrum of factorable matrices are investigated.
Keywords
spectrum; fine spectrum; approximate point spectrum; defect spectrum; compression spectrum; factorable matrices
