Abstract
An abstract simplicial complex is said to be -representable if it records the intersection pattern of a collection of convex sets in . In this paper, we show that -representability of a simplicial complex is equivalent to the existence of a map with certain properties, from a closely related simplicial complex into . This equivalence suggests a framework for proving (and disproving) -representability of simplicial complexes using topological methods such as applications of the Borsuk-Ulam theorem, which we begin to explore.
