A universal exponent for homeomorphs

Abstract:
We prove a uniform bound on the topological Turán number of an arbitrary two-dimensional simplicial complex S: any two-dimensional complex on n vertices with at least CSn3−1/5 facets contains a homeomorph of S, where CS > 0 is a constant depending on S alone. This result, a two-dimensional analogue of a classical one-dimensonal result of Mader, sheds some light on an old problem of Linial from 2006.
