TITLE: Statistical Physics of Citations
SPEAKER: Sid Redner (Boston)
ABSTRACT:
This talk will begin with basic empirical facts about the network of
scientific citations, based on the entire corpus of Physical Review
publications from the past 110 years. Intriguingly, the evolution of
citations appears to be described by linear preferential attachment. A
master equation approach will be developed to characterize this and related
popularity-driven networks. One basic characterization is the citation
distribution of the network, namely, the probability that a publication has a
given number of citations. The conditions that give rise to exponential,
power-law, or more singular citation distributions will be elucidated for
general classes of networks. Comparison between the theory and the citation
data of Physical Review will be made.
