In an interesting recent article [4], J. W. Moon has given a list of properties of the graph L(Bmn) (to be defined more precisely below) and investigated the question of whether these properties ...

In this paper, we study the spectral radius of bipartite graphs. Let 𝐺 be a bipartite graph with 𝑒 edges without isolated vertices. It was known that the spectral radius of 𝐺 is at most the square ...
