A new approach to -positivity for Stanley's chromatic functions
Alexander Paunov, András Szenes
In this paper, we study positivity phenomena for the -coefficients of Stanley's chromatic function of a graph. We introduce a new combinatorial object: the {\em correct} sequenc…

Planar graphs and Stanley's Chromatic Functions
Alexander Paunov
This article is dedicated to the study of positivity phenomena for the chromatic symmetric function of a graph with respect to various bases of symmetric functions. We give a new p…

S-positivity of interval hypergraphs
Alexander Paunov
We prove the s-positivity of the chromatic functions of interval hypergraphs and a conjecture of Taylor~\cite{Taylor15} as a consequence. We also give a new proof of Gasharov's the…
