Dominated sets, microscopic sets and Hausdorff measures

Ondřej Zindulka, Piotr Nowakowski

Let $S$ be a family of sequences of positive numbers that decrease to 0, let $X$ be a metric space and $A \subset X$ . $A$ is said to be $S$ -dominated if, for every $s \in S$ , a coun…

Little lip of a typical function and $σ$ -porosity of graphs

Ondřej Zindulka

For a mapping $f : X \to Y$ between metric spaces the function $lip f : X \to [0, \infty]$ defined by $lip f (x) = lim inf_{r \to 0} \frac{diam f ( B ( x , r ))}{r}$ is…

Mapping Borel sets onto balls and self-similar sets by Lipschitz and nearly Lipschitz maps

Ondřej Zindulka

If $X$ is an analytic metric space satisfying a very mild doubling condition, then for any finite Borel measure $μ$ on $X$ there is a set $N \subseteq X$ such that $μ (N) > 0$ , an ultr…
