On minimally tough chordal graphs

Clément Dallard, Blas Fernández, Gyula Y. Katona +2

Katona and Varga showed that for any rational number $t \in (1/2, 1]$ , no chordal graph is minimally $t$ -tough, while Katona and Khan characterized all minimally $t$ -tough, chordal…

On (almost) $2$ - $Y$ -homogeneous distance-biregular graphs

Blas Fernandez, Safet Penjic

Let $Γ$ denote a bipartite graph with vertex set $X$ , color partitions $Y$ , $Y^{'}$ , and assume that every vertex in $Y$ has eccentricity $D \geq 3$ . For $z \in X$ and a non-negative int…

On some problems regarding distance-balanced graphs

Blas Fernandez, Ademir Hujdurovic

A graph $Γ$ is said to be distance-balanced if for any edge $uv$ of $Γ$ , the number of vertices closer to $u$ than to $v$ is equal to the number of vertices closer to $v$ than to $…
