On tame embeddings of solenoids into 3-space
Solenoids are inverse limits of the circle, and the classical knot theory is the theory of tame embeddings of the circle into 3-space. We make a general study, including certain classification results, of tame embeddings of solenoids into 3-space, seen as the “inverse limits” of tame embeddings of the circle.
Some applications in topology and in dynamics are discussed. In particular, there are tamely embedded solenoids $\Sigma\subset \mathbb R^3$ which are strictly achiral. Since solenoids are non-planar, this contrasts sharply with the known fact that if there is a strictly achiral embedding $Y\subset \mathbb R^3$ of a compact polyhedron $Y$, then $Y$ must be planar.
