Line graphs associated to the maximal graph
Let $R$ be a commutative ring with identity. Let $G(R)$ denote the maximal graph associated to $R$, i.e., $G(R)$ is a graph with vertices as the elements of $R$, where two distinct vertices $a$ and $b$ are adjacent if and only if there is a maximal ideal of $R$ containing both. Let $Gamma(R)$ denote the restriction of $G(R)$ to non-unit elements of $R$. In this paper we study the various graphi...
متن کاملIntroduction to spectral graph theory
We write M ∈ Rn×n to denote that M is an n×n matrix with real elements, and v ∈ Rn to denote that v is a vector of length n. Vectors are usually taken to be column vectors unless otherwise specified. Recall that a real matrix M ∈ Rn×n represents a linear operator from Rn to Rn. In other words, given any vector v ∈ Rn, we think of M as a function which maps it to another vector w ∈ Rn, namely th...

متن کاملApplications of ordinary voltage graph theory to graph embeddability
In part I, we showed that there was an infinite family of graphs not embeddable in the torus in such a way that a free action of any group on any of the graphs extends to a cellular automorphism of the torus. We used a homologically-driven analysis of ordinary voltage graph embeddings. An ordinary voltage graph embedding with voltage group A in a surface encodes a derived embedding of a derived...
