Étude unifiée de problèmes elliptiques dans le cadre höldérien

In this Note we give new results of existence, uniqueness and maximal regularity of the strict solutions for some complete abstract second order differential equations of elliptic type when the second member f is Hölderian. The approach used here generalizes that given in S.G. Krein. To cite this article: A. Favini et al., C. R. Acad. Sci. Paris, Ser. I 341 (2005).
