The project is focused on the study of phenomenon of phase transition in the context of percolation and of spin systems on random triangulations. From a physical point of view it is interesting to study these models because one can interpret these models as systems of gravity-matter. Unlike the classical models, here the environment in which the percolation and spin systems occurs is itself random, this means that the techniques needed to establish the phenomena of phase transition are rather different and challengers.
