Abstract
Let X be a weakly Cauchy normed space in which the parallelogram law holds, C be a bounded closed convex subset of X with one contracting point and T be an {a,b,c}-generalized-nonexpansive mapping from C into C. We prove that the infimum of the set {‖ on C is zero, study some facts concerning the \{a,b,c\}-generalized-nonexpansive mapping and prove that the asymptotic center of any bounded sequence with respect to C is singleton. Depending on the fact that the \{a,b,0\}-generalized-nonexpansive mapping from C into C has fixed points, accordingly, another version of the Browder's strong convergence theorem for mappings is given.
