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 ...

Knowledge graphs are often used to store interlinked descriptions of entities – objects, events, situations or abstract concepts – while also ...

Graphitizing carbons are soft and non-porous, while non-graphitizing carbons are hard, low density materials. Non-graphitizing carbons are otherwise known as chars, hard carbons or, more colloquially, charcoal. Glassy carbon is also an example of a non-graphitizing carbon material. The precursors for graphitizing carbons pass through a fluid ...
15 de out. de 2015 · When I first drew this graph in 2012, I did not recognize it, and I put it aside. But three years later, I asked again, and Matt Enlow responded that the graph resembled the Franklin graph.
Formale Darstellung Der Franklin-Graph.. Percy Heawood vermutete 1890, dass für ein gegebenes Geschlecht g > 0 die minimale Anzahl der benötigten Farben für die Färbung aller Graphen auf der Oberfläche einer orientierbaren Mannigfaltigkeit dieses Geschlechts (oder äquivalent dazu die Färbung einer Zerlegung dieser Fläche in einfach zusammenhängende Flächen) gegeben ist durch:
