Abstract: In this paper we solve the following problem posed by Schmets and Valdivia: Under which conditions does there exist an extension operator from the space ${\mathscr E} (F) $ of the Whitney jets on a closed set $ F \subset{\mathbb{R}} ^n $ to ${\mathscr E}({\mathbb{R}}^n)$ so that the extended functions are real analytic outside $ F $?
