Nous donnons une condition nécessaire et suffisante pour qu’une fonction analytique dans ait une partie réelle dans la classe . Cette condition généralise la condition classique de Zygmund ; on donne aussi d’autres conditions suffisantes.
We give a necessary and sufficient condition for an analytic function in to have real part in class . This condition contains the classical one of Zygmund; other variants are also given.
