AbstractNew topological operations are introduced in order to recover the generalized Dyck equations presented by D. Arquès et al. in another way for the generating functions of maps and colored maps, by decomposing maps topologically and bijectively. By repeatedly applying the operations which made it possible to reveal the generalized Dyck equations for the successive transformed maps, one-to-one correspondences are obtained between maps (colored or not) of indeterminate genus and trees (colored or not) whose vertices can be labelled with several labels, following rules that we will define. These bijections provide us with a coding of these maps.RésuméDe nouvelles opérations topologiques sont introduites afin de nous permettre de retrouve...
