Abstract
We construct a collection of numerical invariants for approximately
transitive (AT) actions (of Z). We use them (sometimes
supplemented by other invariants) to show that members of various
one-parameter families of AT actions are mutually non-isomorphic. In
particular, we construct continua of AT systems that are not
conjugate to their inverses.
