DESCRIPTION:Title: <a href="https://researchseminars.org/talk/agstanford/1
 33/">Representations of rigid matroids</a>\nby Matt Baker (Georgia Tech) a
 s part of Stanford algebraic geometry seminar\n\nLecture held in 383-N.\n\
 nAbstract\nWe give a new proof\, along with some generalizations\, of a fo
 lklore theorem - attributed to Laurent Lafforgue - that a rigid matroid (i
 .e.\, a matroid whose base polytope is indecomposable) has only finitely m
 any projective equivalence classes of representations over any given field
 . A key ingredient in the proof is a generalization of the category of com
 mutative rings which we call *bands*.\n
