Positivity of chromatic symmetric functions associated with Hessenberg functions of bounce number 3

Soojin Cho, Jaehyun Hong

We give a proof of Stanley-Stembridge conjecture on chromatic symmetric functions for the class of all unit interval graphs with independence number 3. That is, we show that the ch…

An analogue of chromatic bases and $p$ -positivity of skew Schur $Q$ -functions

Soojin Cho, JiSun Huh, Sun-Young Nam

We investigate chromatic symmetric functions in the relation to the algebra $Γ$ of symmetric functions generated by Schur $Q$ -functions. We construct natural bases of $Γ$ in terms…
