The Tutte symmetric matrix of a graph

Foster Tom, Aarush Vailaya

We provide a matrix-based formula for the Tutte symmetric function of a graph. In particular, for any graph $G$ with a designated head and tail vertex, we describe an infinite matr…

Linear relations on star coefficients of the chromatic symmetric function

Rosa Orellana, Foster Tom

We prove that the coefficient of the star $st_{2 1^{n - 2}}$ in the chromatic symmetric function $X_{G}$ determines whether a connected graph $G$ is $2$ -connected. We also pr…
