A tensor's spectral bound on the clique number
Chunmeng Liu, Changjiang Bu
In this paper, we study the spectral radius of the clique tensor A(G) associated with a graph G. This tensor is a higher-order extensions of the adjacency matrix of G. A lower boun…

On a generalization of the spectral Mantel's theorem
Chunmeng Liu, Changjiang Bu
Mantel's theorem is a classical result in extremal graph theory which implies that the maximum number of edges of a triangle-free graph of order . In 1970, E. Nosal obtained a s…
