Query: Chromatic quasisymmetric functions and Hessenberg varieties   We discuss three distinct topics of independent interest; one in enumerative
combinatorics, one in symmetric function theory, and one in algebraic geometry.
The topic in enumerative combinatorics concerns a q-analog of a generalization
of the Eulerian polynomials, the one in symmetric function theory deals with a
refinement of the chromatic symmetric functions of Stanley, and the one in
algebraic geometry deals with Tymoczko's representation of the symmetric group
on the cohomology of the regular semisimple Hessenberg variety of type A. Our
purpose is to explore some remarkable connections between these topics.
