Sažetak
Let S be a projective plane with 3 holes. We prove that there is an exhaustion of the curve complex C(S) by a sequence of finite rigid sets. As a corollary, we obtain that the group of simplicial automorphisms of C(S) is isomorphic to the mapping class group Mod(S). We also prove that C(S) is quasi-isometric to a simplicial tree.
