Ein Graph ist in der Graphentheorie eine abstrakte Struktur, die eine Menge von Objekten zusammen mit den zwischen diesen Objekten bestehenden Verbindungen repräsentiert. Die mathematischen Abstraktionen der Objekte werden dabei Knoten (auch Ecken) des Graphen genannt. Die paarweisen Verbindungen zwischen Knoten heißen Kanten (manchmal auch Bögen). Die K… WebDegree (graph theory) In graph theory, the degree (or valency) of a vertex of a graph is the number of edges that are incident to the vertex; in a multigraph, a loop contributes 2 to a …

WebIn graph theory, an expander graph is a sparse graph that has strong connectivity properties, quantified using vertex, edge or spectral expansion. Expander constructions have spawned research in pure and applied mathematics, with several applications to complexity theory, design of robust computer networks, and the theory of error-correcting … WebThe Journal of Graph Theoryis devoted to a variety of topics in graph theory, such as structural results about graphs, graph algorithms with theoretical emphasis, and discrete optimization on graphs.

WebMar 24, 2024 · Blocks arise in graph theoretical problems such as finding unit-distance graphs and the graph genus of connected graphs. For example, a connected graph is unit-distance if and only if each of its blocks is unit-distance and the graph coarseness of a graph is the sum of the coarsenesses of its blocks. See also WebIn a stricter sense, geometric graph theory studies combinatorial and geometric properties of geometric graphs, meaning graphs drawn in the Euclidean plane with possibly intersecting straight-line edges, and … Webandré krischke 2014. graph theory german translation linguee. graphen und netzwerktheorie grundlagen methoden. für s studium grundlagen und methoden der. carl hanser verlag ...
