Opinion formation in the kinetic exchange models
In this talk I will present the minimal multi-agent model [LCCC, Phys. Rev. E 82, 056112 (2010)] for the collective dynamics of opinion formation in the society, which was based on the kinetic exchange dynamics studied in the context of income, money or wealth distributions in a society. This model has an intriguing spontaneous symmetry breaking transition to polarized opinion state starting from non-polarized opinion state. I will also briefly review the simple variants and extensions of this model that have been proposed recently by others.
