Hall--Littlewood expansions of chromatic quasisymmetric polynomials using linked rook placements
Jang Soo Kim, Seung Jin Lee, Meesue Yoo
In this work, we obtain a Hall--Littlewood expansion of the chromatic quasisymmetric function arising from a natural unit interval order and describe the coefficients in terms of l…
