This ensures all the vertices are connected and hence the graph contains the maximum number of edges. In short, a directed graph needs to be a complete graph in order to contain the maximum number of edges. In graph theory, there are many variants of a directed graph. To make it simple...
in P if and only if x is an endpoint of e in G. This poset is called the incidence poset of G. In this paper, we consider the function M(p, d) defined for p, d ⩾ 2 as the maximum number of edges a graph G can have when it has p ...

In this paper, using the Gallai–Edmonds Structure Theorem, we obtain a characterization of graphs each of whose edges belongs to at most one maximum matching. Introduction Graphs considered in this paper are connected and simple. For standard graph-theoretical notation and terminology, we refer ...
In this thesis a problem of determining the maximum number of cycles for the following classes of graphs is considered: triangle-free graphs; K_r-free graphs; graphs with m edges; graphs with n vertices and m edges; multigraphs with m edges and multigraphs with n vertices and m edges. 年...

in a graph that are all connected to one another. Take a look at the simple graph in Figure 1. The graph has nine nodes and 13 edges. The graph is unweighted (there are no priorities associated with the edges) and undirected (all edges are bidirectional). Nodes 2, 4 and 5 form a ...

In the section we prove two simple results that illustrate some of the methods we will use later in the paper. The first is a Kahn–Zhao type result (though substantially easier to prove) concerning the minimum number of independent sets in a d-regular graph. We let It(G) be the set ...
