Abstract (VO)
Résumé

We show that Petermichl's dyadic operator $P$ (Petermichl (2000) [8]) is a Calderón–Zygmund-type operator on an adequate metric normal space of homogeneous type. We also compare the maximal operators associated with truncations of the kernel and to the summability of the Haar series.

Nous démontrons que l'opérateur dyadique de Petermichl $P$ est un opérateur de type Calderón–Zygmund sur un espace normal métrique de type homogène. Nous comparons les opérateurs maximaux associés aux troncatures du noyau et à la sommabilité de la série de Haar.
