Using matrix theory, we present a sharp upper bound on the spectral radius of digraphs and strongly connected diagraphs.
In this paper, we introduce the concept of full strongly connected directed graph, give some characterizations of this graph.
The two are strongly connected, however, and they share some of the same characteristics from the viewpoint of understanding the nature of each.
This is, regrettably, very strongly connected with the HIV/AIDS pandemic.
