Statistics Seminars: Preferential attachment with fitness based choice
7 November 2016 14:00 in CM221
We introduce a preferential attachment model with fitness based choice.
We investigate the asymptotic proportion of edges connecting to
vertices of fitness in a set $A$, and show that there is a simple
criterion under which the model displays condensation-type behaviour
similar to that of preferential attachment with multiplicative fitness,
so that the measure which describes the asymptotic proportions of edges
has an atom at the supremum of the fitness support. The model therefore
adds to the list of models displaying condensation-like behaviour.
