Une généralisation automorphe des nombres de Stirling

Let [n] be theset {1,2, *.. , n> and CT a given permutation in S,, the symmetric group on [n]. The (unsigned) Stirling numbers of the first kind enumerate the permutations on En] with k cycles and those of the second kind give the number partitions of [n] having k blocks. In this paper we compute the number of permutations on [n] with k cycles and the number of partitions on [n] having k blocks...

Facteurs Des Suites De Rudin-shapiro Généralisées

Integrating” paperfolding sequences yields generalized Rudin-Shapiro sequences. We study the factors (subwords) of these sequences, giving an (optimal) property of “half-synchronization” and a uniform linear bound for the recurrence function. We also study the powers occurring in these sequences, and we show that the language consisting of all their factors is not contextfree.
