SUMMARY:Algebraic Combinatorics Seminar - Laura Colmenarejo
CLASS:PUBLIC
DESCRIPTION:TITLE: Chromatic symmetric functions of Dyck paths and $q$-roo
 k\ntheory\n\nSpeaker:\n Laura Colmenarejo\n\nAffiliation:\n UMass Amherst\
 n\nZoom:\n Contact Karen Yeats\n\nABSTRACT:\n\nGiven a graph and a set of 
 colors\, a coloring of the graph is a\nfunction that associates each verte
 x in the graph with a color. In\n1995\, Stanley generalized this definitio
 n to symmetric functions by\nlooking at the number of times each color is 
 used and extending the\nset of colors to $\\mathbb{Z}^+$. In 2012\, Share
 shian and Wachs\nintroduced a refinement of the chromatic functions for or
 dered graphs\nas $q$-analogues.
