Abstract

The purpose of this work is to combine percolation and contact process topics to formulate and achieve results in a particle system model that is inspired by the diffusion phenomenon of an innovation in a structured population. More precisely, we proposed a continuous time Markov chain defined in a population represented by the d-dimensional integer lattice. Each agent of population may be in any of the three states belonging to the set {0; 1; 2}. In this model, 0 stands for ignorant, 1 for aware and 2 for adopter. The arguments, that allow to obtain sufficient conditions under which the innovation either becomes extinct or survives with positive probability, will be studied. This involves the study of percolation models and contact process. (AU)
