Melanie Matchett Wood Univ. of Wisconsin-Madison Title: Sandpile groups of random graphs and universality for random abelian groups Abstract: he sandpile group is an abelian group associated to a graph, given as the cokernel of the graph Laplacian. An Erdos Renyi random graph then gives some distribution of random abelian groups. We will discuss results giving the distribution of these sandpile groups of random graphs, and how they fit into a larger framework of universality for random abelian groups, under which random abelian groups constructed from many independent inputs necessarily have a certain universal distribution, in an analog of the central limit theorem for random finite abelian groups.Date: Wednesday, January 24, 2018Time: 4:30 pmLocation: Wean Hall 8220Submitted by: BohmanNote: Refreshments at 4:00 pm, Wean Hall 6220. |
