The closure-complement-frontier problem in saturated polytopological spaces

Sara Canilang, Michael P. Cohen, Nicolas Graese +1

Let $X$ be a space equipped with $n$ topologies $τ_{1}, ..., τ_{n}$ which are pairwise comparable and saturated, and for each $1 \leq i \leq n$ let $k_{i}$ and $f_{i}$ be the associated topolo…

Maximal pseudometrics and distortion of circle diffeomorphisms

Michael P. Cohen

We initiate a study of distortion elements in the Polish groups $\mbox{Diff}_+^k(\mathbb{S}^1)$ ( $1 \leq k < \infty$ ), as well as $\mbox{Diff}_+^{1+AC}(\mathbb{S}^1)$, in terms of max…
