Title: A New Graph Polynomial from the Chromatic Symmetric Function
Speaker: Logan Crew Affiliation: University of Waterloo Zoom: Contact Soffia ArnadottirAbstract:
The chromatic symmetric function X_G of a graph generalizes the chromatic polynomial by distinguishing proper n-colourings by how many times each colour is used. Furthermore, many other natural graph polynomials also arise from specializations of X_G;
