Products of Circulant Graphs Are Metacirculant

open access: yesJournal of Combinatorial Theory, Series B, 2002
Broere and Hattingh studied \(B\)-products of graphs (introduced by Imrich and Izbicki) and proved that the lexicographic product of two circulant graphs is again circulant, but this is not the case with other products. In the present paper any \(B\)-product of two circulant graphs is proved to be a metacirculant graph with parameters that are easily ...

The hyperbolicity constant of infinite circulant graphs [PDF]

open access: yesOpen Mathematics, 2017
If X is a geodesic metric space and x1, x2, x3 ∈ X, a geodesic triangle T = {x1, x2, x3} is the union of the three geodesics [x1x2], [x2x3] and [x3x1] in X.

Combinatorial refinement on circulant graphs

open access: yescomputational complexity, 2022
AbstractThe combinatorial refinement techniques have proven to be an efficient approach to isomorphism testing for particular classes of graphs. If the number of refinement rounds is small, this puts the corresponding isomorphism problem in a low-complexity class. We investigate the round complexity of the two-dimensional Weisfeiler--Leman algorithm on

On Ádám's conjecture for circulant graphs

open access: yesDiscrete Mathematics, 1997
The content of this article is analogous to the one of the author's former paper [J. Comb. Theory, Ser. A 72, No. 1, 118-134 (1995; Zbl 0833.05063)]. Now the author proves the reviewer's conjecture in case of an \(n\) (number of vertices) such that \(n/4\) is a square-free odd integer.

On Embeddings of Circulant Graphs [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2015
A circulant of order $n$ is a Cayley graph for the cyclic group $\mathbb{Z}_n$, and as such, admits a transitive action of $\mathbb{Z}_n$ on its vertices. This paper concerns 2-cell embeddings of connected circulants on closed orientable surfaces.
