In\n1995\, Stanley generalized th is definition to symmetric functions by\nlooking at the number of times ea ch color is used and extending the\nset of colors to $\\mathbb{Z}^+$. In 2 012\, Shareshian and Wachs\nintroduced a refinement of the chromatic func tions for ordered graphs\nas $q$-analogues.\n DTSTAMP:20250521T215937Z END:VEVENT END:VCALENDAR
