Streszczenie
We prove a theorem that generalizes in a way both Michael's Selection Theorem and Dugundji's Simultaneous Extension Theorem. We use it to prove that if $K$ is an uncountable compact metric space and $X$ a Banach space, then $C(K, X)$ is isomorphic to $C(\mathcal{C}, X)$ where $\mathcal{C}$ denotes the Cantor set. For $X=\mathbb{R}$, this gives the well known Milyutin Theorem.
