Firmly nonexpansive and Kirszbraun-Valentine extensions: a constructive approach via monotone operator theory
Heinz H. Bauschke, Xianfu Wang · Contemporary mathematics - American Mathematical Society · 2010
Utilizing our recent proximal-average based results on the constructive extension of monotone operators, we provide a novel approach to the celebrated Kirszbraun-Valentine Theorem and to the extension of firmly nonexpansive mappings.
