DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QMULANTS/23/
 ">Characteristic sets of matroids</a>\nby Dustin Cartwright (University of
  Tennessee) as part of Queen Mary University of London Algebra and Number 
 Theory Seminar\n\n\nAbstract\nA matroid is a combinatorial abstraction of 
 the types of dependence relations that appear both as linear dependence in
  vector spaces and algebraic dependence in field extensions. As not all ma
 troids can be realized in either of these ways\, we can define the linear 
 and algebraic characteristic sets of a matroid as the set characteristics 
 of fields over which the matroid is realizable in a vector space or field 
 extension\, respectively. The focus of my talk will be the possible charac
 teristic sets of matroids. An important tool will be the construction of a
 lgebraic matroids from the ring of endomorphisms of a 1-dimensional connec
 ted algebraic group. This is joint work with Dony Varghese.\n
