Hankel determinants of the Thue-Morse sequence
Annales de l'Institut Fourier, Tome 48 (1998) no. 1, pp. 1-27.

Soit ϵ=(ϵ n ) n0 la suite de Thue-Morse, c’est-à-dire la suite définie par les relations de récurrence :

ϵ 0 = 1 , ϵ 2 n = ϵ n , ϵ 2 n + 1 = 1 - ϵ n .

Soit {| n p |} n1,p0 , la suite double des déterminants de Hankel (modulo 2) associés à la suite de Thue-Morse. Elle vérifie un ensemble complexe de relations de récurrence. On montre qu’elle est 2-automatique. On donne des applications, notamment à l’étude combinatoire de la suite de Thue-Morse et à l’existence de certains approximants de Padé de la série formelle : n0 (-1) ϵ n x n .

Let ϵ=(ϵ n ) n0 be the Thue-Morse sequence, i.e., the sequence defined by the recurrence equations:

ϵ 0 = 1 , ϵ 2 n = ϵ n , ϵ 2 n + 1 = 1 - ϵ n .

We consider {| n p |} n1,p0 , the double sequence of Hankel determinants (modulo 2) associated with the Thue-Morse sequence. Together with three other sequences, it obeys a set of sixteen recurrence equations. It is shown to be automatic. Applications are given, namely to combinatorial properties of the Thue-Morse sequence and to the existence of certain Padé approximants of the power series n0 (-1) ϵ n x n .
