Duality on Noncompact Manifolds and Complements of Topological Knots
Let £ be the image of a topological embedding of Sn~2 into S" .In this paper the homotopy groups of the complement S" -I. are studied.In contrast with the situation in the smooth and piecewise-linear categories, it is shown that the first nonstandard homotopy group of the complement of such …
