The element in the brackets, [ ] is called the representative of the equivalence class. An equivalence class can be represented by any element in that equivalence class. So, in Example 6.3.2 , [S2] = [S3] = [S1] = {S1, S2, S3}. This equality of equivalence classes will be formalized in Lemma 6.3.1.

In formal terms, a directed graph is an ordered pair G = (V, A) where • V is a set whose elements are called vertices, nodes, or points; • A is a set of ordered pairs of vertices, called arcs, directed edges (sometimes simply edges with the corresponding set named E instead of A), arrows, or directed lines. Webhere (x,y) is not an ordered pair, but the name of an edge. If the graph is directed and there is a unique edge e pointing from x to y, then we may write e = (x,y), so E may be …

WebThe self-loop can be described as an edge that connects a vertex to itself. The sub-graph is a type of subset of the directed graph's edge that constitutes a directed graph. If two edges of a graph connect with the same ordered pair of vertices, these edges will be in parallel. The number of an edge can also be known as the length of a cycle or ...
