Now to define our problem more exactly. The line graph of the complete bipartite graph on sets with m and n vertices, denoted by L (Bmn), is the graph with mn vertices given by all ordered pairs (i, j ...

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 ...
