====== The Extension Space Conjecture for Oriented Matroids ======

===== Abstract for the Combinatorics and Geometry and Topology Seminars 2011 February 8 =====

The Extension Space Conjecture is perhaps the most succinct manifestation of the great meta-question of oriented matroid theory: "How well do oriented matroids model real vector arrangements"? I'll give an overview of the problem and the limited progress that's been made.
