 Incoming links: Threshold function for a monotone graph property

Giant component 2026-10-07
 View more
A giant component in a sequence of random graphs on n vertices has order proportional to n. Its existence can change at a threshold function for a monotone graph property. A giant component need not contain every vertex, and its uniqueness requires proof for the model in question.

For a monotone graph property P=(Pn​), a function p∗(n) is a threshold function for a monotone graph property when
p/p∗⟶0⟹P(G(n,p)∈Pn​)⟶0,
(1)
and
p/p∗⟶∞⟹P(G(n,p)∈Pn​)⟶1.
