    Pour f holomorphe sur la boule-unité ouverte B de \({\mathbb{C}}^ n,\) on pose \(Rf(z)=\sum^{n}_{j=1}z_ j\frac{\partial f}{\partial z_ j}(z)\) et on itère l'opérateur R. Si R nf\(\in H\) 1(B): \(1\circ)\) le développement de f en série de polynomes homogènes converge normalement sur la frontière S de B, vers un prolongement continu de f à \(\bar B,\) encore noté f; \(2\circ)\) si I est un intervalle et \(\phi\) : \(I\to S\) de classe \({\mathcal C}^ 2,\) alors \(f\circ \phi\) est absolument continue \(I\to {\mathbb{C}}\).
