Query: Isomorphisms between curve graphs of infinite-type surfaces are
  geometric   Let $\phi:\mathcal{C}(S)\to\mathcal{C}(S')$ be a simplicial isomorphism
between the curve graphs of two infinite-type surfaces. In this paper we show
that in this situation $S$ and $S'$ are homeomorphic and $\phi$ is induced by a
homeomorphism $h:S\to S'$.
