Polyhedral geometry of refined $q, t$ -Catalan numbers

Matthias Beck, Mitsuki Hanada, Max Hlavacek +3

We study a refinement of the $q, t$ -Catalan numbers introduced by Xin and Zhang (2022, 2023) using tools from polyhedral geometry. These refined $q, t$ -Catalan numbers depend on a ve…

The $e$ -positivity of the chromatic symmetric function for twinned paths and cycles

Esther Banaian, Kyle Celano, Megan Chang-Lee +7

The operation of twinning a graph at a vertex was introduced by Foley, Hoàng, and Merkel (2019), who conjectured that twinning preserves $e$ -positivity of the chromatic symmetric f…
