Combinatorial aspect of fashion
Simulations are performed according to the Axelrod model of culture
dissemination, with modified mechanism of repulsion. Previously, repulsion was
considered by Radillo-Diaz et al (Phys. Rev. E 80 (2009) 066107) as dependent
on a predefined threshold. Here the probabilities of attraction and repulsion
are calculated from the number of cells in the same states. We also investigate
the influence of some homogeneity, introduced to the initial state. As the
result of the probabilistic definition of repulsion, the ordered state
vanishes. A small cluster of a few percent of population is retained only if in
the initial state a set of agents is prepared in the same state. We conclude
that the modelled imitation is successful only with respect to agents, and not
only their features
The Simmel effect and babies names
Simulations of the Simmel effect are performed for agents in a scale-free
social network. The social hierarchy of an agent is determined by the degree of
her node. Particular features, once selected by a highly connected agent,
became common in lower class but soon fall out of fashion and extinct.
Numerical results reflect the dynamics of frequency of American babies names in
1880-2011.Comment: 11 pages, 7 figure
