Abstract
We construct a complete Riemannian surface that admits no triangulation such that the inclusion is a quasi-isometry, where is the simplicial 1-skeleton of . Our construction is without boundary, has arbitrarily large systole, and furthermore, there is no embedded graph such that is a quasi-isometry. This answers a question of Georgakopoulos.
