Removing Symmetry in Circulant Graphs and Point-Block Incidence Graphs
An automorphism of a graph is a mapping of the vertices onto themselves such that connections between respective edges are preserved. A vertex v in a graph G is fixed if it is mapped to itself under every automorphism of G. The fixing number of a graph G

On the energy of some circulant graphs [PDF]
We give an explicit construction of circulant graphs of very high energy. This construction is based on Gauss sums. We also show the Littlewood conjecture can be used to establish new result for a certain class of circulant ...

On the Metric Index of Circulant Networks–An Algorithmic Approach
A vertex v of a graph G uniquely determines (resolves) a pair (v1, v2) of vertices of G if the distance between v and v1 is different from the distance between v and v2.

Combinatorial refinement on circulant graphs [PDF]
The 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 ...

Colouring Clique-Hypergraphs of Circulant Graphs
Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)A clique-colouring of a graph G is a colouring of the vertices of G so that no maximal clique of size at least two is ...

Perfect matching transitivity of circulant graphs.
A graph G is perfect matching transitive, shortly PM-transitive, if for any two perfect matchings M1 and M2 of G, there is an automorphism f : V(G)↦V(G) such that fe(M1)=M2, where fe(uv)=f(u)f(v).

Two families of circulant nut graphs [PDF]
A circulant nut graph is a non-trivial simple graph whose adjacency matrix is a circulant matrix of nullity one such that its non-zero null space vectors have no zero elements.

Eccentricity-Based Topological Invariants of Some Chemical Graphs
Topological index is an invariant of molecular graphs which correlates the structure with different physical and chemical invariants of the compound like boiling point, chemical reactivity, stability, Kovat’s constant etc.
