Abstract

Let XX and YY be Banach or normed linear spaces and FXF\subset X a closed set. We apply our recent extension theorem for vector-valued Baire one functions arXiv:1512.03717 to obtain an extension theorem for vector-valued functions f ⁣:FYf\colon F\to Y with pre-assigned derivatives, with preservation of differentiability (at every point where the pre-assigned derivative is actually a derivative), preservation of continuity, preservation of (pointwise) Lipschitz property and (for finite dimensional domain XX) preservation of strict differentiability and global (eventually local) Lipschitz continuity.
