A note about certain geometric properties of the norm of a dual Banach space. (English) Zbl 0623.46009
The following renorming theorem for a Banach space E is proved: if E is weakly compactly generated, then E can be equivalently renormed in such a way that $$E^*$$ is weak* locally uniformly convex. Some consequences of this result are proved. [For related results see G. Godefroy, S. Troyanski, J. H. M. Whitfield and V. Zizler, J. Funct. Anal. 52, 344-352 (1983; Zbl 0517.46010)].
