We define a map nu between the symmetric group S_n and the set of pairs of Dyck paths of semilength n. We show that the map nu is injective when restricted to the set of 1234-avoiding permutations and characterize the image of this map.

Abstract
We define a map nu between the symmetric group S_n and the set of pairs of Dyck paths of semilength n. We show that the map nu is injective when restricted to the set of 1234-avoiding permutations and characterize the image of this map.File in questo prodotto:
