Discrete Applied Math Seminar By Stephanie van Willigenburg: The (3+1)-Free Conjecture of Chromatic Symmetric Functions

Speaker:

Stephanie van Willigenburg, University of British Colombia

Title:

The (3+1)-Free Conjecture of Chromatic Symmetric Functions

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.

The Discrete Applied Math seminar will be held most Fridays from 3:30 p.m. - 4:30 p.m. on Zoom during the Spring 2022 semester.
