Title: On the modulus of <i>u</i>‐convexity of Ji Gao
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.Read More
