The graph connectivity is the measure of the robustness of the graph as a network. In a connected graph, if any of the vertices are removed, the graph gets disconnected. Then the graph is called a vertex-connected graph. On the other hand, when an edge is removed, the graph becomes disconnected. It is known as an edge-connected graph.

In the mathematical area of graph theory, a clique ( / ˈkliːk / or / ˈklɪk /) is a subset of vertices of an undirected graph such that every two distinct vertices in the clique are adjacent.

Nowhere in the definition is there talk of dots or lines. A three-dimensional hypercube graph showing a Hamiltonian path in red, and a longest induced path in bold black.. In graph theory, a path in a graph is a finite or infinite sequence of edges which joins a sequence of vertices which, by most definitions, are all distinct (and since the vertices are distinct, so are the edges). A directed path (sometimes called …Graph Theory - Isomorphism. A graph can exist in different forms having the same number of vertices, edges, and also the same edge connectivity. Such graphs are called isomorphic graphs. Note that we label the graphs in this chapter mainly for the purpose of referring to them and recognizing them from one another.

Two graphs that are isomorphic must both be connected or both disconnected. Example 6 Below are two complete graphs, or cliques, as every vertex in each graph is connected to every other vertex in that graph. As a special case of Example 4, Figure 16: Two complete graphs on four vertices; they are isomorphic.

Cycle detection is a particular research field in graph theory. There are algorithms to detect cycles for both undirected and directed graphs. There are scenarios where cycles are especially undesired. An example is the use-wait graphs of concurrent systems. In such a case, cycles mean that exists a deadlock problem.Definition. An Eulerian trail, or Euler walk, in an undirected graph is a walk that uses each edge exactly once. If such a walk exists, the graph is called traversable or semi-eulerian.. An Eulerian cycle, also called an Eulerian circuit or Euler tour, in an undirected graph is a cycle that uses each edge exactly once. If such a cycle exists, the graph is called …The graph G G of Example 11.4.1 is not isomorphic to K5 K 5, because K5 K 5 has (52) = 10 ( 5 2) = 10 edges by Proposition 11.3.1, but G G has only 5 5 edges. Notice that the number of vertices, despite being a graph invariant, does not distinguish these two graphs. The graphs G G and H H: are not isomorphic.Bipartite Graph - If the vertex-set of a graph G can be split into two disjoint sets, V 1 and V 2, in such a way that each edge in the graph joins a vertex in V 1 to a vertex in V 2, and there are no edges in G that connect two vertices in V 1 or two vertices in V 2, then the graph G is called a bipartite graph. Complete Bipartite Graph - A ...A complete graph is an undirected graph in which every pair of distinct vertices is connected by a unique edge. In other words, every vertex in a complete graph is adjacent to all other vertices. A complete graph is denoted by the symbol K_n, where n is the number of vertices in the graph.
