A selection of books and papers that present models similar to the church growth models. Some papers model social epidemics and have a similar concept to the “enthusiast” in the Limited Enthusiasm model. These works, drawn mainly from mathematical sociology, are part of the mathematical credibility of the project.

### General

The book by Coleman became the definitive volume in mathematical sociology. He put forward models of innovation diffusion which have been extensively investigated since. It is particularly relevant for the church growth models as he proposed the use of the epidemic equations for modelling social diffusion, i.e. the active period of those spreading the phenomena is limited. Bartholomew gives stochastic models of such diffusion.

### Theory of Social Diffusion

American Journal of Sociology 78 (6): 1360–1380.*Presents the thesis that weak ties between groups are more influential in social diffusion than*strong ties within groups because, for example, there is less redundancy in weak ties,*which open up new groups of susceptible people*.

### Population Biology

Although not directly connected with social diffusion, like the mathematics of epidemics, a number of concepts are transferable in the field.
