DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Matroids/28/
 ">Motivic Zeta functions of hyperplane arrangements</a>\nby Max Kutler (Oh
 io State University) as part of Matroids - Combinatorics\, Algebra and Geo
 metry Seminar\n\nLecture held in Room 210 The Fields Institute.\n\nAbstrac
 t\nWe associate to any matroid a motivic zeta function. If the matroid is 
 representable by a complex hyperplane arrangement\, then thiscoincides wit
 h the motivic Igusa zeta function of the arrangement.Although the motivic 
 zeta function is a valuative invariant which is finer than the characteris
 tic polynomial\, it is not obvious how one should extract meaningful combi
 natorial data from the motivic zeta function. One strategy is to specializ
 e to the topological zeta function. I will survey what is known about thes
 e functions and discuss some open questions.\n
