Abstract
We aim to study stochastic systems that model the spreading of an item of information or disease in a group of individuals. For the rumour models, one of our purposes is to prove large deviation theorems for the final fraction of ignorant individuals in the population. Furthermore, we plan to investigate the behaviour of these models on random networks and of some processes in which various rumours spread. We will also study epidemic and rumour models that are formulated through interacting random walks systems on graphs.In the case of infinite graphs, we intend to study the questions of local and global survival of processes in random environment.In the case of finite graphs, we are interested in working with models in which the particles are able to be immunized and to earn lives at random during their lifetimes.
