【 摘 要 】

We give some sufficient conditions for the Dominguez-Lorenzo condition in terms of the James constant, the Jordan-von Neumann constant, and the coefficient of weak orthogonality. As a consequence, we obtain fixed point theorems for multivalued nonexpansive mappings. (c) 2007 Elsevier Inc. All rights reserved.
