Invertibility, Often

Ethan Akin, Benjamin Weiss

By using a similar pattern of arguments, we show that in four categories the collection of isomorphisms forms a residual subset of the space of morphisms. We first consider surject…

Universality of G-subshifts with specification

Tomasz Downarowicz, Benjamin Weiss, Mateusz Więcek +1

Let $G$ be an infinite countable amenable group and let $(X, G)$ be a $G$ -subshift with specification, containing a free element. We prove that $(X, G)$ is universal, i.e., has posit…

The emergence of 4-cycles in polynomial maps over the extended integers

Andrew Best, Patrick Dynes, Steven J. Miller +2

Let $f (x) \in Z [x]$ ; for each integer $α$ it is interesting to consider the number of iterates $n_{α}$ , if possible, needed to satisfy $f^{n_{α}} (α) = α$ . The sets $\{α, f(α),…
