WebbFinite graph infinite graph. Bipartite graphs: A bipartite graph, also called a bigraph, is a set of graph vertices decomposed into two disjoint sets such that no two graph vertices within the same set are adjacent. Incidence and Degree: When a vertex vi is an end vertex of some edge ej, vi and ej are said to incident with each other. Webb1 feb. 1988 · Embeddings of infinite graphs in surfaces without boundary are considered. Cellular embeddings are studied in details. Each rotation system of a locally finite graph G gives rise to a cellular embedding of G, and every cellular embedding with all 2-cells of finite size can be obtained in this way.The graphs which admit cellular embeddings with … WebbA problem by Diestel is to extend algebraic flow theory of finite graphs to infinite graphs with ends.

WebbIn the language of graph theory, the Ramsey number is the minimum number of vertices, v = R(m, n), such that all undirected simple graphs of order v, contain a clique of order m, or an independent set of order n. Ramsey's theorem states that such a number exists for all m and n . By symmetry, it is true that R(m, n) = R(n, m). WebbA network is a graph with edge-weights that need not be symmetric. This book presents an autonomous theory of harmonic functions and potentials defined on a finite or infinite network, on the lines of axiomatic potential theory. Random walks and electrical networks are important sources for the advancement of the theory.

WebbIf the set of vertices and the set of edges of a graph are both finite, the graph is called finite, otherwise infinite. An infinite graph has infinitely many edges but possibly only finitely many vertices (e.g., two vertices can be connected by infinitely many edges.) … Webb1 okt. 2008 · Our approach permits the extension to infinite graphs of standard results about finite graph homology - such as cycle-cocycle duality and Whitney's theorem, Tutte's generating theorem, MacLane's ...
