Paper detail

A counterexample to a conjecture on Schur positivity of chromatic symmetric functions of trees

We show that no tree on twenty vertices with maximum degree ten has Schur positive chromatic symmetric function, thereby providing a counterexample to a conjecture from the paper "Schur and e-positivity of trees and cut vertices".
