There's also a simpler, weaker construction in a similar spirit to the Mycielskian which lets us find a graph with χ ( G) = r, and ω ( G) < r (note the Mycielskian gives ω ( G) = 3 ). For r = 3, the cycle on five vertices works, and then simply add vertices which are connected to all existing vertices by induction to give a ... In graph theory, a cycle graph or circular graph is a graph that consists of a single cycle, or in other words, some number of vertices (at least 3, if the graph is simple) connected in a closed chain. The cycle graph with n vertices is called Cn. The number of vertices in Cn equals the number of edges, and … See more There are many synonyms for "cycle graph". These include simple cycle graph and cyclic graph, although the latter term is less often used, because it can also refer to graphs which are merely not acyclic. … See more A directed cycle graph is a directed version of a cycle graph, with all the edges being oriented in the same direction.

In the mathematical field of graph theory, the Erdős–Rényi model refers to one of two closely related models for generating random graphs or the evolution of a random network. These models are named after Hungarian mathematicians Paul Erdős and Alfréd Rényi, who introduced one of the models in 1959. Edgar Gilbert introduced the other model contemporaneously and independently of Erdős a… Web4 GRAPH THEORY { LECTURE 2 STRUCTURE AND REPRESENTATION PART A Structural Equivalence for Simple Graphs Def 1.1.
