Strictly singular non-compact diagonal operators on HI spaces

Functional Analysis 2008-07-16 v1

Abstract

We construct a Hereditarily Indecomposable Banach space \eqsd\eqs_d with a Schauder basis \seq{e}{n} on which there exist strictly singular non-compact diagonal operators. Moreover, the space \mcL\diag(\eqsd)\mc{L}_{\diag}(\eqs_d) of diagonal operators with respect to the basis \seq{e}{n} contains an isomorphic copy of (N)\ell_{\infty}(\N).
