SUMMARY:Algebraic Combinatorics Seminar - Steph van Willigenburg
CLASS:PUBLIC
DESCRIPTION:TITLE: The e-positivity of chromatic symmetric functions\n\nSp
 eaker:\n Steph van Willigenburg\n\nAffiliation:\n University of British Co
 lumbia\n\nZoom:\n Contact Karen Yeats\n\nABSTRACT:\n\nThe chromatic polyno
 mial was generalized to the chromatic symmetric\nfunction by Stanley in hi
 s seminal 1995 paper. This function is\ncurrently experiencing a flourishi
 ng renaissance\, in particular the\nstudy of the positivity of chromatic s
 ymmetric functions when expanded\ninto the basis of elementary symmetric f
 unctions\, that is\,\ne-positivity.
