Theory of finite and infinite graphs

WebbThe theory of infinite graphs appears at present to be in an even more incomplete state than the theory of finite graphs, in the sense that some of the work which has been done for finite graphs has either not been extended to infinite graphs or been extended only to some infinite graphs, e.g., locally finite ones. WebbAs the title suggests the meeting brought together workers interested in the interplay between finite and infinite combinatorics, set theory, graph theory and logic. It used to be that infinite set theory, finite combinatorics and logic could be viewed as quite separate and independent subjects.

Webb23 okt. 1995 · For finite graphs, we present an O (mn) algorithm for computing the similarity relation of a graph with n vertices and m edges (assuming m/spl ges/n). For effectively presented infinite graphs, we present a symbolic similarity-checking procedure that terminates if a finite similarity relation exists.

Let v be a vertex of a (finite or infinite) tree T other than a path. A branch of T at v is a maximal subtree having v as a leaf. A branch path of T at v is a branch that is either a path or a 1-way infinite path. flip up glasses for makeup
