SUMMARY:Graphs and Matroids Seminar - Josephine Reynes
CLASS:PUBLIC
DESCRIPTION:TITLE: The Tutte Polynomial\, Bipartite Representations of Grap
 hs\, and\nGrid Walking \n\nSPEAKER:\n Josephine Reynes\n\nAFFILIATION:\n 
 University of Waterloo\n\nLOCATION:\n MC 5417\n\nABSTRACT: The Tutte Polyn
 omial has many equivalent definitions. It can\nbe defined by a deletion-co
 ntraction relation with the terms\ndetermined by the sequence of contracti
 ons\, deletions\, loops\, and\nisthmi. This definition is independent of e
 dge order. Another\ndefinition relies on a fixed edge ordering and examine
 s the edge\nactivities over maximal spanning forests. There is a direct\nr
 elationship between edge activity and deletion/contraction for a\ngiven ed
 ge ordering. Furthermore\, the monomials of the Tutte\npolynomial can be i
 nterpreted as grid walks. This allows for an\napproach to the Tutte polyno
 mial on hypergraphs by examining the grid\nwalks of the bipartite represe
 ntation of the graph.
