The models proposed here can be classified into three groups; a)models of communciation networks, b)models of balancing processes, and c)a model of social power. The first group are descriptive and treats with changes in frequencies of communciation in a group. The second group consists of two subgroups: one is direct generalization of Flament(1963)'s model with respect to the probabilities of transition and the other allows for the neutralization of opinions. The third model is generalization of Harary(1959)'s model and its appcliation to Jacobs and Campbell(1961)'s experiment is presented as an example of its uses.
