On the chromatic symmetric homology for star graphs
Laura Pierson
The chromatic symmetric function is a power series that encodes the proper colorings of a graph by assigning a variable to each color and a monomial to each coloring such…

A power sum expansion for the Kromatic symmetric function
Laura Pierson
The chromatic symmetric function is a symmetric function generalization of the chromatic polynomial of a graph, introduced by Stanley (1995). Stanley gave an expansion formul…

Counting induced subgraphs with the Kromatic symmetric function
Laura Pierson
The chromatic symmetric function is a sum of monomials corresponding to proper vertex colorings of a graph . Crew, Pechenik, and Spirkl (2023) recently introduced a -th…
