It is proved that: for every Banach space $X$ which has uniformly normal structure there exists a $k > 1$ with the property: if $A$ is a nonempty bounded closed convex subset of $X$ and $T : A \to A$ is an asymptotically regular mapping such that $\underset{n \to \infty}{lim inf} | | | T^{n} | | | < k,$ where $| | | T | | |$ is the Lipschitz constant (norm) of $T$ , then $T$ has a fixed point in $A$ .

We introduce the classes of nearly contraction mappings and nearly asymptotically nonexpansive mappings. The class of nearly contraction mappings includes the class of contraction mappings, but the class of nearly asymptotically nonexpansive mappings contains the class of asymptotically nonexpansive mappings and is contained in the class of mappings of asymptotically nonexpansive type. We study the existence of fixed points and the structure of fixed point sets of mappings of these classes in Banach...

We prove the following theorem: Let p > 1 and let E be a real p-uniformly convex Banach space, and C a nonempty bounded closed convex subset of E. If $T = T_{s} : C \to C : s \in G = [0, \infty)$ is a Lipschitzian semigroup such that $g = l i m i n f_{G ∋ α \to \infty} i n f_{G ∋ δ \geq 0} 1 / α ʃ_{0}^{α} ∥ T_{β + δ} ∥^{p} d β < 1 + c$ , where c > 0 is some constant, then there exists x ∈ C such that $T_{s} x = x$ for all s ∈ G.
