Abstract

We construct a complete Riemannian surface Σ\Sigma that admits no triangulation GΣG\subset \Sigma such that the inclusion G(1)ΣG^{(1)} \hookrightarrow \Sigma is a quasi-isometry, where G(1)G^{(1)} is the simplicial 1-skeleton of GG. Our construction is without boundary, has arbitrarily large systole, and furthermore, there is no embedded graph GΣG\subset\Sigma such that G(1)ΣG^{(1)} \hookrightarrow \Sigma is a quasi-isometry. This answers a question of Georgakopoulos.
