摘要
We prove that functions analytic in the unit disk and continuous up to the boundary are dense in the de Branges-Rovnyak spaces induced by the extreme points of the unit ball of H-infinity. Together with previous theorems, it follows that this class of functions is dense in any de Branges-Rovnyak space. (C) 2017 Academie des sciences. Published by Elsevier Masson SAS.
