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, KÃ¡lmÃ¡n…

On the characterizations of $D_{k} \ D_{k - 2}$

Jing Zeng, Lihua You, Xinghui Zhao +1

The determinant of a tournament $T$ , denoted by $det (T)$ , is defined as the determinant of the skew-adjacency matrix of $T$ . It is well-known that $det (T)$ is equal to $0$ if $n$ …
