Uniform extension of definable $C^{m, ω}$ -Whitney jets

Adam Parusiński, Armin Rainer

We show that definable Whitney jets of class $C^{m, ω}$ , where $m$ is a nonnegative integer and $ω$ is a modulus of continuity, are the restrictions of definable $C^{m, ω}$ -functions…

Definable Lipschitz selections for affine-set valued maps

Adam Parusiński, Armin Rainer

Whitney's extension problem, i.e., how one can tell whether a function $f : X \to R$ , $X \subseteq R^{n}$ , is the restriction of a $C^{m}$ -function on $R^{n}$ , wa…
