Graphs and Matroids Seminar

Title: Representable orientable matroids that are not real-representable

Speaker:  Rutger Campbell
Affiliation: University of Waterllo
Room: MC 5417

Abstract: In this talk we will have a brief introduction to oriented matroids and their relation to real-representability. Then, for each odd prime power q>3, we will construct a GF(q)-representable oriented matroid that is not real-representable.
