Journal ArticleDOI
Optimal multiplexed sensing: bounds, conditions and a graph theory link.
TL;DR: It is shown that graph theory can be harnessed for finding ideal codes that best increase the signal to noise ratio, while accounting for the signal dependency of noise, by the use of strongly regular graphs.
Journal ArticleDOI
On quasi-strongly regular graphs
TL;DR: In this paper, the quasi-strongly regular graphs of grade 2 were studied and a spectral gap-type result for the eigenvalues of a strongly regular graph was derived.
Journal ArticleDOI
Bounding the gap between extremal Laplacian eigenvalues of graphs
TL;DR: In this article, the authors investigate the gap between the extremal non-trivial Laplacian eigenvalues of a connected graph (that is λ n and λ 2 ) and find that the gap is closely related to the average density of cuts in a graph.

Conjectured bounds for the sum of squares of positive eigenvalues of a graph
TL;DR: In this article, Hong's spectral radius upper bound for connected graphs was proved for various classes of graphs, including bipartite, regular, complete $q$-partite, hyper-energetic, and barbell graphs.
Journal ArticleDOI
Conjectured bounds for the sum of squares of positive eigenvalues of a graph
TL;DR: The conjecture that for connected graphs n - 1 ź s + ź 2 m - n + 1 , where s + denotes the sum of the squares of the positive eigenvalues, is proved for various classes of graphs.
