 5 Is there a proper etiquette for asking an author for their (mathematical) software? 4 Prove that $C^1([a,b])$ with the $C^1$- norm is a Banach Space 4 Showing a sequence $x_{n+1} = Tx_n$ forms a contraction mapping 4 If $f^{-1}(G)$ is open in $X$ for every open set $G$ in $Y$, then $f$ is continuous. Question on proof. 3 Show convergence of a sequence of continuous functions $f_n$ to a continuous function $f$ does not imply convergence of corresponding integrals.
