Spectral radius and (globally) rigidity of graphs in $R^2$
TL;DR: In this paper , the authors study the rigidity of 2-connected graphs in R 2 from the viewpoint of adjacency eigenvalues, and provide sufficient conditions for a 3-connected graph with given minimum degree to be globally rigid.
Journal ArticleDOI
The signed graphs with all but at most three eigenvalues equal to −1
Yongang Wang,Dan Li,Huiqiu Lin +2 more
TL;DR: In this article , the authors characterize the signed graphs for which the adjacency matrices have at most three eigenvalues unequal to −1, where the eigenvalue of a signed graph is defined as the sum of all the vertices of the graph.
State transfer on integral mixed circulant graphs
Xingwu Song,Huiqiu Lin +1 more
TL;DR: In this article , the existence of perfect state transfer and multiple state transfer on integral mixed circulant graphs was investigated and necessary and sufficient conditions for such transfer were provided, respectively.

Remoteness and distance eigenvalues of a graph
TL;DR: Aouchiche and Hansen as discussed by the authors gave lower bounds on the distance eigenvalues of a connected graph of order n, where n is the number of vertices in the graph, and k is the diameter of the graph.
Journal ArticleDOI
Toughness, hamiltonicity and spectral radius in graphs
TL;DR: In this article , a spectral condition for a graph to be 1-tough with minimum degree δ and to be t-hard, respectively, was proposed. But it is not known whether the spectral condition can guarantee the existence of a Hamiltonian cycle among t-soft graphs.
