$(q, t)$ -chromatic symmetric functions

Tatsuyuki Hikita

By using level one polynomial representations of affine Hecke algebras of type $A$ , we obtain a $(q, t)$ -analogue of the chromatic symmetric functions of unit interval graphs which…

A proof of the Stanley--Stembridge conjecture

Tatsuyuki Hikita

We give a probabilistic interpretation of the coefficients of the elementary symmetric function expansion of the chromatic quasisymmetric function for any unit interval graph. As a…
