Friday, September 25, 2009 — 3:30 PM to 4:30 PM EDT

Matroids, Diophantine equations, and decidability

Speaker: Jim Geelen
Affiliation: University of Waterloo
Room: Mathematics & Computer Building (MC) 5158

Abstract:

For a field F we consider the problem of deciding whether or not a given matroid is representable over the field. We show that this is equivalent to the problem of deciding whether or not a given system of Diophantine equations has a solution over F. This is joint work with Shalev Ben David. 

The talk will be accessible to a general mathematics audience. Knowledge of matroid theory is not required.
