Théories conformes et systèmes désordonnés

Abstract : This thesis concerns the analysis of two-dimensional systems with randomness using conformal field theory techniques. The first chapter is devoted to a brief review of different methods in conformal field theory. The second chapter is a presentation of different types of disordered systems which will be studied. One will found also a brief summary of know results. In the next chapters, we present applications of these methods to the case of Ising, Potts and multicritical models. Finaly in the last chapter we analyse the effect of disorder in some systems with a first order phase transition.
