Maximum nullity and zero forcing of circulant graphs
The zero forcing number of a graph has been applied to communication complexity, electrical power grid monitoring, and some inverse eigenvalue problems.

Characterization of strongly regular integral circulant graphs by spectral approach
The integral circulant graph ICGn(D) has the vertex set Zn = {0, 1, 2, . . . , n? 1} and vertices a and b are adjacent if gcd(a ? b, n) ? D, where D ? Dn, Dn = {d : d | n, 1 ? d < n}.

Incidence and Laplacian matrices of wheel graphs and their inverses
It has been an open problem to find the Moore-Penrose inverses of the incidence, Laplacian, and signless Laplacian matrices of families of graphs except trees and unicyclic graphs.

On the Broadcast Independence Number of Circulant Graphs [PDF]
An independent broadcast on a graph $G$ is a function $f: V \longrightarrow \{0,\ldots,{\rm diam}(G)\}$ such that $(i)$ $f(v)\leq e(v)$ for every vertex $v\in V(G)$, where $\operatorname{diam}(G)$ denotes the diameter of $G$ and $e(v)$ the eccentricity ...

Stability of circulant graphs [PDF]
The canonical double cover $\mathrm{D}(Γ)$ of a graph $Γ$ is the direct product of $Γ$ and $K_2$. If $\mathrm{Aut}(\mathrm{D}(Γ))=\mathrm{Aut}(Γ)\times\mathbb{Z}_2$ then $Γ$ is called stable; otherwise $Γ$ is called unstable. An unstable graph is nontrivially unstable if it is connected, non-bipartite and distinct vertices have different neighborhoods.

On Hamilton decompositions of infinite circulant graphs [PDF]
The natural infinite analogue of a (finite) Hamilton cycle is a two-way-infinite Hamilton path (connected spanning 2-valent subgraph). Although it is known that every connected 2k-valent infinite circulant graph has a two-way-infinite Hamilton path ...
