Abstract and Applied Analysis, 2003, vol. 2003, 1-6

Abstract:

We consider the modulus of u -convexity of a Banach space introduced by Ji Gao (1996) and we improve a sufficient condition for the fixed-point property (FPP) given by this author. We also give a sufficient condition for normal structure in terms of the modulus of u -convexity.
