Smoothness and its equivalents in weakly compactly generated Banach spaces

K. John; Václav Zizler

Abstract Some equivalent properties of the existence of Frechet smooth norms in weakly compactly generated (WCG) Banach spaces are shown. Heredity of WCG property in such spaces is proved. The property of having a shrinking Markusevic basis is hereditary in all Banach spaces. Projections in WCG spaces and their duals are studied.

A renorming of dual spaces

K. John; Václav Zizler

If Banach spacesX,X* are both weakly compactly generated, thenX has an equivalent norm whose dual onX* is locally uniformly rotund.
