description | <p/> <p>Let <inline-formula><graphic file="1687-1812-2005-359216-i1.gif"/></inline-formula> be a nonempty closed convex subset of a reflexive real Banach space <inline-formula><graphic file="1687-1812-2005-359216-i2.gif"/></inline-formula> which has a uniformly Gâteaux differentiable norm. Assume that <inline-formula><graphic file="1687-1812-2005-359216-i3.gif"/></inline-formula> is a sunny nonexpansive retract of <inline-formula><graphic file="1687-1812-2005-359216-i4.gif"/></inline-formula> with <inline-formula><graphic file="1687-1812-2005-359216-i5.gif"/></inline-formula> as the sunny nonexpansive retraction. Let <inline-formula><graphic file="1687-1812-2005-359216-i6.gif"/></inline-formula>, <inline-formula><graphic file="1687-1812-2005-359216-i7.gif"/></inline-formula>, be a family of nonexpansive mappings which are weakly inward. Assume that every nonempty closed bounded convex subset of <inline-formula><graphic file="1687-1812-2005-359216-i8.gif"/></inline-formula> has the fixed point property for nonexpansive mappings. A strong convergence theorem is proved for a common fixed point of a family of nonexpansive mappings provided that <inline-formula><graphic file="1687-1812-2005-359216-i9.gif"/></inline-formula>, <inline-formula><graphic file="1687-1812-2005-359216-i10.gif"/></inline-formula>, satisfy some mild conditions.</p> |
