On the coefficients of interior and exterior polynomials of polymatroids

Xiaxia Guan, Xian'an Jin, Tianlong Ma +1

The Tutte polynomial is an important invariant of graphs and matroids. Chen and Guo \emph{[Adv. in Appl. Math. 166 (2025) 102868.]} proved that for a $(k + 1)$ -edge connected graph $…

Coefficients of univariate Tutte polynomials with one variable fixed

Tianlong Ma, Xiaxia Guan, Xian'an Jin +1

It is well known that the 2-variable Tutte polynomial of a graph $G$ includes chromatic polynomial and flow polynomial of $G$ , i.e. the cases of $y = 0$ and $x = 0$ . In 2013, Kálmán in…
