Abstract

Linkings of higher dimensional disjoint singular spheres in euclidean space ℝm are compared with linkings in the sphereS m. Somewhat surprisingly, link homotopy inS m can be interpreted as a special case of link homotopy in ℝm. This leads to a considerable refinement of standard invariants such as the generalized Milnor invariants.
