WebNov 30, 2015 · The definition addresses a relationship between two edges. It does not imply or require that only two edges can or should have the relationship of being adjacent edges. Similarly we speak of two triangles being congruent without suggesting that there can only be two congruent triangles. – hardmath Nov 30, 2015 at 17:03

WebIn graph theory, an ear of an undirected graph G is a path P where the two endpoints of the path may coincide, but where otherwise no repetition of edges or vertices is allowed, so every internal vertex of P has degree two in G.An ear decomposition of an undirected graph G is a partition of its set of edges into a sequence of ears, such that the one or two … WebThe connection between vertices and edges can be described by a relation on V × E, such that each edge is incident with one or two vertices (just one if you're not inclined to allow … Web2 are parallel edges, but the edges e 2 and e 5 are not called parallel edges. Exercise 1.3.1. Find all the parallel edges Example 1.3.1. Notice that a multigraph allows for multiple edges between a pair of vertices, but does not allow for loops. In some applications it may be desirable to illustrate all the connections between the vertices. lavanky
