Abstract
In this part of our paper we present several new theorems concerning the existence of common fixed points of asymptotically regular uniformly lipschitzian semigroups.
Highlights
Let (X, · ) be a Banach space and C a subset of X
Every asymptotically regular sequence {xn} with a weakly compact conv {xn} there exists a weakly convergent to w subsequence {xni} such that (i) r (w, {xni}) ≤ θ · diama ({xn}), (ii) w − y ≤ ra (y, {xni}) for every y ∈ X
We find i0 such that for all i ≥ i0 we have
Summary
Let (X, · ) be a Banach space and C a subset of X. [30] Let X be a uniformly convex Banach space, C a nonempty bounded closed convex subset of X and T : C → C a k-lipschitzian mapping with k < γ1, where γ1 > 1 is the solution of the equation γ1 1 − δ [7] Let X be a Banach space X with uniform normal structure and C a nonempty bounded closed convex subset of X.
