Characterization of Trees with Maximum Security

Alex S. A. Alochukwu, Audace A. V. Dossou-Olory, Fadekemi J. Osaye +5

The rank (also known as protection number or leaf-height) of a vertex in a rooted tree is the minimum distance between the vertex and any of its leaf descendants. We consider the s…

Outerplanar graphs with positive Lin-Lu-Yau curvature

George Brooks, Fadekemi Osaye, Anna Schenfisch +2

In this paper, we show that all simple outerplanar graphs $G$ with minimum degree at least $2$ and positive Lin-Lu-Yau Ricci curvature on every edge have maximum degree at most $9$ …

On edge-weighted mean eccentricity of graphs

Peter Johnson, Fadekemi Janet Osaye

Let $G$ be a connected edge-weighted graph of order $n$ and size $m$ . Let $w : E (G) \to R^{\geq 0}$ be the weighting function. We assume that $w$ is normalised, that…

The average eccentricity of a graph with prescribed girth

Fadekemi Janet Osaye

Let $G$ be a connected graph of order $n$ . The eccentricity $e (v)$ of a vertex $v$ is the distance from $v$ to a vertex farthest from $v$ . The average eccentricity of $G$ is the me…

Average eccentricity, minimum degree and maximum degree in graphs

P. Dankelmann, F. J. Osaye

Let $G$ be a connected finite graph with vertex set $V (G)$ . The eccentricity $e (v)$ of a vertex $v$ is the distance from $v$ to a vertex farthest from $v$ . The average eccentricity…
