Knotted families from graspers
arXiv:2307.14028 · doi:10.1112/topo.12337
Abstract
For any smooth manifold of dimension we construct explicit classes in homotopy groups of spaces of embeddings of either an arc or a circle into , in every degree that is a multiple of , and show that they are detected in the Taylor tower of Goodwillie and Weiss. The classes are obtained from families of string links constructed in the -ball.
