Theory of finite and infinite graphs
WebbA rigidity theory is developed for countably infinite simple graphs in $${\\mathbb {R}}^d$$ R d . Generalisations are obtained for the Laman combinatorial characterisation of … Webb1 jan. 1976 · The first such theorem due to Brooks [3] states that for any finite graph G, x (G) ~< 1 + A (G); furthermore, if G is connected, then equality holds if and only if G is a complete graph or an odd cycle. Often this result is too crude, hence Wilf [10] found an upper bound for x (G) which is more global.

WebbA complete graph contains all possible edges. Finite graph. A finite graph is a graph in which the vertex set and the edge set are finite sets. Otherwise, it is called an infinite … 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.) …
Webb28 sep. 2024 · Most commonly in graph theory it is implied that the graphs discussed are finite. If the graphs are infinite, that is usually specifically stated. In graph theory, the degree (or valency) of a vertex of a graph is the number of edges incident to the vertex, with loops counted twice.
Webb1 nov. 2010 · This result is best possible up to the additive constant—we construct an (infinite) planar graph of maximum degree Delta1, whose spectral ra- dius is √ 8Delta1 −16. This generalizes and improves several previous results and solves an open problem proposed by Tom Hayes. Sim- ilar bounds are derived for graphs of bounded genus. re 2 remake interactive mapWebb1 dec. 1982 · In the present paper the basic definitions are given and some theorems from the finite theory of spectra are extended to the infinite case.
