Regular models of hyperelliptic curves

Let $K$ be a complete discretely valued field of residue characteristic not $2$ and $O_K$ its ring of integers. We explicitly construct a regular model over $O_K$ with strict normal crossings of any hyperelliptic curve $C\mathrm{/}K:y^2=f(x)$. For this purpose, we introduce the new notion of ‘‘MacLane cluster picture’’, that aims to be a link between clusters and MacLane valuations.
