To make the statement of the Theorem 2.4 more clear, please replace the last sentence of Theorem 2.4 by the following sentences.
Then there exists an orbit $\{x_{n}\}$ of $G$ at $x_{0}$ and $x\in X$ such that $\lim_{n\to\infty}x_{n}=x$.
Moreover, $x$ is a fixed point of $G$ if and only if $f(\xi)=d(\xi,G\xi)$ is lower semi-continuous at $x$.
To make the statement of the Theorem 2.9 more clear, please replace the last sentence of Theorem 2.9 by the following sentences.
Then there exists an orbit $\{x_{n}\}$ of $G$ at $x_{0}$ and $x\in X$ such that $\lim_{n\to\infty}x_{n}=x$.
Moreover, $\{x\}=Gx$ if and only if $f(\xi)=\delta(\xi,G\xi)$ is lower semi-continuous at $x$.
