Abstract:
Scientific communities are characterized by strong stratification. The
highly skewed frequency distribution of citations of published scientific
papers suggests a relatively small number of active, cited papers embedded
in a sea of inactive and uncited papers. We propose an analytically soluble
model which allows for the death of nodes. This model provides an excellent
description of the citation distributions for live and dead papers in the
SPIRES database. Further, this model suggests a novel and general mechanism
for the generation of power law distributions in networks whenever the
fraction of active nodes is small.
