Gromov's knot distortion
Gromov's knot distortion

John Pardon, Princeton University
Gromov defined the distortion of an embedding of S1 into R3 and asked whether every knot could be embedded with distortion less than 100. There are (many) wild embeddings of S1 into R3 with finite distortion, and this is one reason why bounding the distortion of a given knot class is hard. I will show how to give a nontrivial lower bound on the distortion of torus knots. I will also mention some natural conjectures about the distortion, for example that the distortion of the (2,p)-torus knots is unbounded.
