The application of generalization modulus of convexity in fixed point theory
Cui Yun-an · Journal of Natural Science of Heilongjiang University · 2009
By the study of the relationship between generalized modulus of convexity and the coefficient of weak orthogonality,sufficient condition for Banach space X have uniform normal structure is obtained,which imply the single valued nonexpansive mapping to have fixed point,moreover which also imply the multivalued nonexpansive mapping to have fixed point.
