Abstract.

In this paper we will consider Foata map as a function which associates another permutation, known as F(δ ), to each permutation δ = δ 1 δ 2 ⋅ ⋅ ⋅ δ m of the integers {1, 2, . . . ,m}, in such a way that the number of cycles of δ is equal to the number of left to right minima of F(...

We consider some particular cases of the general problem which consists of stating if a shift vector of m elements corresponds to a permutation of the same number of objects. Shifts are defined as the steps each element in a given permutation must perform in order to reach its natural position,...
