Spectral radius, edge-disjoint cycles and cycles of the same length
TL;DR: In this paper, the authors give spectral conditions to guarantee the existence of two edge disjoint cycles and two cycles of the same length, which can be seen as spectral analogues of Erdős and Posa's size condition.

A spectral condition for the existence of a pentagon in non-bipartite graphs
TL;DR: In this paper, it was shown that if G is a non-bipartite graph with order n ≥ 21 and ρ ( G ) ≥ ρ( K ⌈ n − 2 2 2 ⌉, ⌊ n−2 2 2⌋ • K 3 ), then G contains a pentagon unless G ≅ K ⊈ n−1 2 2 3 2 2 ό( n−3 2 2 ).
Journal ArticleDOI

Zejun Huang,Huiqiu Lin +1 more
TL;DR: The maximum and minimum sizes of digraphs with a given clique numbers as well as thedigraphs that attain these extremal sizes are determined.
Journal ArticleDOI
A note on (signless) Laplacian spectral ordering with maximum degrees of graphs
TL;DR: For two connected nonregular (n, m) -graphs G and G, the authors showed that if Δ (G ) ≥ 2 m − (n − 1 ) δ (G ), δ(G ) + 1 + 1 and Δ ( G ) > Δ(G ), then μ (G) > μ(G), and q (G), G > q(G) − δ, G + 1 − 1 + δ δ, G − 1.
Journal ArticleDOI
Spectral radius and [a,b]-factors in graphs
TL;DR: In this article , the authors provided spectral conditions for the existence of an odd [1, b]-factor in a connected graph with minimum degree δ and for an [a,b]-factor of a graph.
