Abstract

To interpret interacting particle system style models as social dynamics, suppose each pair {i,j} of individuals in a finite population meet at random times of arbitrary specified rates νij, and update their states according to some specified rule. The averaging process has real-valued states and the rule: upon meeting, the values Xi(t),Xj(t) are replaced by ½(Xi(t)+Xj(t)),½(Xi(t)+Xj(t)). It is curious this simple process has not been studied very systematically. We provide an expository account of basic facts and open problems.
