Abstract: Several limit theorems for contact processes with cooperation mechanisms were given from the case where the base maps are homogeneous trees and complete graphs. First, the solution of the limit equation of the contact process with the cooperation mechanism was obtained under the homogeneous tree at a given point and a given time. Next, by means of the idea of the fixed point of the differential equation, the critical value of the cooperation mechanism parameter β was obtained. Then, changing the base map to the complete map, the contact process with the cooperation mechanism was studied, and the density of diseased points at a given moment was obtained when the dimensionality tended to infinity. Finally, as a special case of the contact process of the mechanism, the contact process under the classic mechanism (that is β=0) was reviewed, and the limit function of the number of diseased points was derived.
