Continuous functions on Berkovich spaces

Abstract

Let $k$ be a perfect complete valued field with a nontrivial non-archimedean norm $|\cdot|$ and $\omega\in k$ with $0<|\omega|<1.$ Let $X$ be a reduced and normal $k$-analytic space. Then $O^{\circ}\simeq \lim\limits_{\leftarrow}O^{\circ}/\omega^n.$
