Some results of the Lipschitz constant of 1-Field on
We study the relations between the Lipschitz constant of -field and the
Lipschitz constant of the gradient canonically associated with this -field.
Moreover, we produce two explicit formulas that make up Minimal Lipschitz
extensions for -field. As consequence of the previous results, for the
problem of minimal extension by continuous functions from to
, we also produce analogous explicit formulas to those of
Bauschke and Wang. Finally, we show that Wells's extensions of -field are
absolutely minimal Lipschitz extension when the domain of -field to expand
is finite. We provide a counter-example showing that this result is false in
general.Comment: E.L.G. and T.V.P. are partially supported by the ANR (Agence
