Singular Graphs with Dihedral Group Action

Ali Sltan Ali AL-Tarimshawy, J. Siemons

Let $Γ$ be a simple undirected graph on a finite vertex set and let $A$ be its adjacency matrix. Then $Γ$ is {\it singular} if $A$ is singular. The problem of characterising singul…

Singular Graphs on which the Dihedral Group Acts Vertex Transitively

Ali Sltan Ali AL-Tarimshawy

Let $Γ$ be a simple connect graph on a finite vertex set $V$ and let $A$ be its adjacency matrix. Then $Γ$ is said to be \textit{singular} if and only if $0$ is an eigenvalue of $A…

Singular graphs

Ali Sltan AL-Tarimshawy

Let $Γ$ be a simple graph on a finite vertex set $V$ and let $A$ be its adjacency matrix. Then $Γ$ is said to be singular if and only if $0$ is an eigenvalue of $A .$ The nullity (s…
