The first part of this thesis concerns the area of random maps, which is a topic in between probability theory, combinatorics and statistical physics. Our work complements several results of convergence of various classes of random maps to the Brownian map, which is a random compact metric space. More precisely, we prove that the scaling limit of a map which is uniformly distributed over the class of rooted planar maps with n edges, equipped with the graph distance rescaled by (2n)^(−1/4), is, in the Gromov-Hausdorff sense, the Brownian map. To establish this result, the main arguments are the use of a combinatorial bijection between bipartite maps and multitype trees, together with convergence theorems for Galton-Watson multitype trees. We...
