Inertia and spectral symmetry of eccentricity matrices of some clique trees

Xiaohong Li, Jianfeng Wang, Maurizio Brunetti

The eccentricity matrix $E (G)$ of a connected graph $G$ is obtained from the distance matrix of $G$ by leaving unchanged the largest nonzero entries in each row and each c…

On distance-balanced generalized Petersen graphs

Gang Ma, Jianfeng Wang, Sandi Klavžar

A connected graph $G$ of diameter $diam (G) \geq ℓ$ is $ℓ$ -distance-balanced if $∣ W_{x y} ∣ = ∣ W_{y x} ∣$ for every $x, y \in V (G)$ with $d_{G} (x, y) = ℓ$ , where $W_{x y}$ is the…

The strong chromatic index of 1-planar graphs

Yiqiao Wang, Ning Song, Jianfeng Wang +1

The chromatic index $χ^{'} (G)$ of a graph $G$ is the smallest $k$ for which $G$ admits an edge $k$ -coloring such that any two adjacent edges have distinct colors. The strong chromatic…
