the giant component phase transition Flashcards
sprinkling graph
nq_n tends to λ as n grows
G1,G2 independent realisations of G(n,q_n) and G(n,n^-5/4)
G3 their union
then whp
|Cmax(G3)|/n>1-η(λ)-ε
phase transition
if λ<=1 lots of small components
if λ>1 whp there exists a giant component
order of G
number of vertices
exploration process
discover the component of I, by looking at its neighbours and then the neighbours of the neighbours
breadth-first order
root, children, first child of root, second child of root, …, first child of first child, … etc
states
active, inactive, neutral
random walk associated via
number of active members
binomial branching process
n choose k * p^k (1-p)^n-k
poisson branching process
e^-λ λ^k/k!
total number
inf {t: S_t=0}
