Abstract

Given a uniformly convergent sequence of ambient isotopies (Hn)nN(H_n)_{n\in\mathbb{N}}, bijectivity of the limit function HH_\infty together with a minor compactness condition guarantees that HH_\infty is also an ambient isotopy. By offloading the uniform convergence hypothesis to a more diagrammatic condition, we obtain sufficient conditions for performing countably-many Reidemeister moves. We use this to construct examples of tame knots with countably-many crossings and discuss what distinguishes these from similar-looking wild curves.
