Chromatic symmetric homology is a lift of the chromatic symmetric function for graphs to a homological setting, and its Frobenius characteristic is a q,t generalization of the chromatic symmetric function. We exhibit three pairs of graphs where each pair has the same chromatic symmetric function but distinct homology over C as Sn-modules. We also show that integral chromatic symmetric homology contains torsion, and based on computations, conjecture that Z2-torsion in bigrading (1,0) detects nonplanarity in the graph.}, journal={ADVANCES IN APPLIED MATHEMATICS}, author={Chandler, Alex and Sazdanovic, Radmila and Stella, Salvatore and Yip, Martha}, year={2023}, month={Sep} }

The periodicity property and the dilogarithm identities concerning these Y-systems were conjectured by Tateo, and only a part of them have been proved so far. In this paper we formulate these Y-systems by the polygon realization of cluster algebras of types A and D, and prove the conjectured periodicity and dilogarithm identities in full generality. As it turns out, there is a wonderful interplay among continued fractions, triangulations of polygons, cluster algebras, and Y-systems.}, number={10}, journal={TRANSACTIONS OF THE AMERICAN MATHEMATICAL SOCIETY}, author={Nakanishi, Tomoki and Stella, Salvatore}, year={2016}, month={Oct}, pages={6835–6886} }
