Density of the level sets of the metric mean dimension for homeomorphisms

Abstract

Let $N$ be an $n$-dimensional compact riemannian manifold, with $n\ge 2$. In this paper, we prove that for any $\alpha \in [0,n]$, the set consisting of homeomorphisms on $N$ with lower and upper metric mean dimensions equal to $\alpha$ is dense in $\text{Hom}(N)$. More generally, given $\alpha ,\beta \in [0,n]$, with $\alpha \le \beta$, we show the set consisting of homeomorphisms on $N$ with lower metric mean dimension equal to $\alpha$ and upper metric mean dimension equal to $\beta$ is dense in $\text{Hom}(N)$. Furthermore, we also give a proof that the set of homeomorphisms with upper metric mean dimension equal to $n$ is residual in $\text{Hom}(N)$.
