Abstract
We show that if an open arc J of the boundary of a Jordan domain \({\varOmega }\) is rectifiable, then the derivative \(\varPhi '\) of the Riemann map \(\varPhi :D\;\rightarrow \;{\varOmega }\) from the open unit disk D onto \({\varOmega }\) behaves as an \(H^1\) function when we approach the arc \(\varPhi ^{-1}(J')\), where \(J'\) is any compact subarc of J.
Résumé
Nous démontrons que si un arc ouvert J de la frontière d’ un domaine de Jordan \(\varOmega \) est rectifiable, alors la dérivée \(\varPhi ^{\prime }\) de la fonction de Riemann \(\varPhi \) entre le disque unité ouvert D sur \(\varOmega \) se comporte comme une fonction de classe de Hardy \(H^1\), quand on approche le sous-ensemble \(\varPhi ^{-1}(J^{\prime })\) où \(J^{\prime }\) est un sous-ensemble compact de J.
