Oriented Matroids from Wild Spheres

Hochstättler, Winfried (1995) Oriented Matroids from Wild Spheres.
Technical Report , 14 p.


In a recent article [5] we gave a lattice-theoretical characterization of oriented matroids in terms of the zero-map. In this paper we derive from that characterization a generalization of one direction of the Topological Representation Theorem using hyperspheres which may be wildly embedded, thus solving a problem presented by A. Björner et al. [Oriented Matroids (1993), Exercise 5.6.c].
