Abstract

We prove a topological extension of Dirac's theorem suggested by Gowers in 2005: for any connected, closed surface , we show that any two-dimensional simplicial complex on vertices in which each pair of vertices belongs to at least facets contains a homeomorph of spanning all the vertices. This result is asymptotically sharp, and implies in particular that any 3-uniform hypergraph on vertices with minimum codegree exceeding contains a spanning triangulation of the sphere.
