  We introduce a model of polarization in networks as a unifying framework for
the measurement of polarization that covers a wide range of applications. We
consider a sufficiently general setup for this purpose: node- and
edge-weighted, undirected, and connected networks. We generalize the axiomatic
characterization of Esteban and Ray (1994) and show that only a particular
instance within this class can be used justifiably to measure polarization in
networks.
