Sur la variation quadratique totale de la suite des parties fractionnaires des quotients d'un nombre réel positif par les nombres entiers naturels consécutifs
We give an asymptotic formula for the quadratic total variation of the sequence of fractional parts of the quotients of a positive real number by the consecutive natural numbers

Comportement local moyen de la fonction de Brjuno
We describe the average behaviour of the Brjuno function in the neighbourhood
of any given point of the unit interval. In particular, we show that its
Lebesgue set is the set of Brjuno numbers and we fi nd the asymptotic behaviour
of the modulus of continuity of its integral.Comment: A para\^itre dans Fundamenta Mathematica
