SUMMARY:Algebraic Combinatorics Seminar - Logan Crew
CLASS:PUBLIC
DESCRIPTION:TITLE: Edge Deletion-Contraction in the Chromatic and Tutte Sy
 mmetric\nFunctions\n\nSpeaker:\n Logan Crew\n\nAffiliation:\n University o
 f Waterloo\n\nZoom:\n Contact Karen Yeats\n\nABSTRACT:\n\nWe consider symm
 etric function analogues of the chromatic and Tutte\npolynomials on graphs
  whose vertices have positive integer weights. We\nshow that in this setti
 ng these functions admit edge\ndeletion-contraction relations akin to thos
 e of the corresponding\npolynomials\, and we use these relations to give e
 numerative and/or\ninductive proofs of properties of these functions.
