The (3+1)-free conjecture of chromatic symmetric functions
Stephanie van Willigenburg (U. of British Columbia, Canada)
Date & time: Wednesday, 09 March 2022 at 3:30PM - 4:30PM
Abstract: The chromatic symmetric function, dating from 1995, is a generalization of the chromatic polynomial. A famed conjecture on it, called the Stanley-Stembridge (3+1)-free conjecture, has been the focus of much research lately. In this talk we will be introduced to the chromatic symmetric function, the (3+1)-free conjecture, new cases, and tools for resolving it, and answer another question of Stanley of whether the (3+1)-free conjecture can be widened. This talk requires no prior knowledge.
