1. Introduction. A self-mapping F of a Banach space F is said to be nonexpansive provided \\Tx— Ty\\ ^ \\x— y\\ for all x, y e E, and is said to be quasi-nonexpansive provided that if Tp=p then \\Tx— p\\ = \\x— p\\ for all x e E (i.e., Fis nonexpansive about each of its fixed points). Nonexpansive mappings are clearly quasi-non-expansive, and linear(More)
