Title: Self-dual axioms for infinite matroids on lattices

Speaker: Peter Nelson
Affiliation: University of Waterloo
Location: MC 5479

Abstract: In an informal sequel to my recent Tutte colloquium on the topic, I will talk about axiomatizing infinite matroids with a modular lattice in place of the usual ground set. I will present three sets of axioms that characterize these objects; two of the axiom sets are self-dual.
