Opinion formation with upper and lower bounds

We investigate the opinion formation with upper and lower bounds. We formulate the binary exchange of opinions between two individuals, and effects of the self-thinking and political party using the relativistic Boltzmann-Vlasov type equation with the randomly perturbed motion. The convergent form of the distribution function is determined by the balance between the cooling rate via the binary exchange of opinions between two individuals and the concentration of opinions by the political party, and heating rate via the self-thinking.
