%0 Journal Article %T The mapping class group orbit of a multicurve %A Rasmus Villemoes %J Mathematics %D 2008 %I arXiv %X Given a set equipped with a transitive action of a group, we define the notion of an almost invariant coloring of the set. We consider the mapping class group orbit of a multicurve on a compact surface, and prove that in the case of genus at least two, no such almost invariant coloring exists. Conversely, in the case of a closed torus, one may find almost invariant colorings using arbitrarily many colors. %U http://arxiv.org/abs/0802.3000v2
