✦ Synopsis

We characterize the class ((c 0 ) T , (c 0 ) T ) where T = (t nk ) ∞ n,k=0 and T = (t nk ) ∞ n,k=0 are triangles. Using the Hausdorff measure of noncompactness, we define the class of compact operators given by matrices in ((c 0 ) T , (c 0 ) T ). Furthermore we give a sufficient condition for a matrix operator to be a Fredholm operator on (c 0 ) T .

## Abstract The aim of this note is to study the spectral properties of the LUECKE's class __R__ of operators __T__ such that ‖(__T – zI__)^−1^‖=1/__d__(__z, W__(__T__)) for all __z__∉__CLW__(__T__), where __CLW__(__T__) is the closure of the numerical range __W__(__T__) of __T__ and __d__(__z, W__

In this paper, after a characterization of a class of bounded Fredholm operators on Banach spaces, we investigate the essential spectra of closed, densely defined linear operators on L spaces. The obtained results are used to describe the p essential spectra of one-dimensional transport equations wi
