Some sufficient conditions for fixed points of multivalued nonexpansive mappings in Banach spaces
Xi Wang, Chip ng Zhang, Yunan Cui · Journal of Mathematical Inequalities · 2017
In this paper, we show some sufficient conditions on a Banach space X concerning the generalized von Neumann-Jordan constant, the coefficient R(1,X) and the coefficient of weak orthogonality, which imply the existence of fixed points for multivalued nonexpansive mappings.
