... B; b) be a map. ... The definition of shape fibration uses the approximate homotopy lifting property (AHLP) applied to ANRresolutions of maps. ... E (in proM) is an ANRresolution of E if and only if (E; q) = lim /\Gamma E and the following condition holds: for each i and any neighborhood U of q i (E) in E i there exists j ? ... A shape fibration p : E ! ... B between compact metric spaces is a 0dimensional shape fibration if and only if there exists an ANRresolution p = fp i g : E \Lambda ...

The beamer class Manual for version 3.06. \begin{frame} \frametitle{There Is No Largest Prime Number} \framesubtitle{The proof uses \textit{reductio ad absurdum}.} \begin{theorem} There is no largest prime number. \end{theorem} \begin{proof} \begin{enumerate} \item<1-| alert@1> Suppose $p$ were the largest prime number. \item<2-> Let $q$ be the product of the first $p$ numbers. \item<3-> Then $q+1$ is not divisible by any of them. \item<1-> Thus $q+1$ is also prime and greater than $p$.\qedhere
