Within the spectrum of arithmetic, graph idea which experiences a mathe matical constitution on a collection of parts with a binary relation, as a well-known self-discipline, is a relative newcomer. In fresh 3 many years the fascinating and quickly growing to be sector of the topic abounds with new mathematical devel opments and critical functions to real-world difficulties.

En ) such that t(ei ) = o(ei+1 ) (Fig. 11). We write o(c) = c(0) = o(e1 ) for the origin of c, and c(k) = t(ek ). We put t(c) = t(en ) for the terminus of c and |c| = n for the length of c. It is often said that c joins o(c) and t(c). We also write c = (en , . . , e1 ) for the inversion of c. A path c with o(c) = t(c) is said to be closed. We regard a vertex x ∈ V as a path of length 0, which is called the point path at x and denoted by 0/ x . Notice that a path of length n in X is a morphism from the segment graph [0, n] with vertices 0, 1, .

32 3 Generalities on Graphs Fig. 14 Spanning trees The following three statements for a graph X are equivalent: 1. X is a tree. 2. For any two vertices x and y, there is one and only one geodesic joining x and y. 3. Every edge separates X. As for separating edges of a graph X, we have: (a) Every edge separates X into at most two connected components. (b) An edge e does not separate X if and only if there exists a circuit in X containing e. (c) Let E1 be the set of edges that separate X into two connected components.

N into X. Likewise, a closed path of length n is a morphism from the circuit graph Cn (the circle with n vertices) into X (Fig. 12). A graph is connected if for any two vertices x and y, there is a path c with o(c) = x and t(c) = y. Note that X is connected if and only if X as a cell complex is connected (actually, arcwise connected). Our graphs are supposed to be connected unless otherwise stated. The following fact is sometimes useful. Fig. 11 A path Fig. 4 Paths 31 Fig. 1. For a non-empty subset A ⊂ V , if x ∈ A ⇒ t(e) ∈ A holds for every e ∈ Ex , then A = V .
