Abstract:
We continue the investigations started in [1]–[4], where
weakly convex sets and set-valued maps with weakly convex images were
studied. Sufficient conditions are found for the existence of a Lipschitz
parametrization for a set-valued map with solidly smooth (generally,
non-convex) images. It is also shown that the set-valued
$\varepsilon$-projection on a weakly convex set and the unit outer normal
vector to a solidly smooth set satisfy, as set functions, the Lipschitz
condition and the Hölder condition with exponent $1/2$, respectively,
relative to the Hausdorff metric.
