Extract

1. The following results are special cases of theorems of Irwin and Zeeman, respectively (see (4), (9), (10)).

(a) Let V be a (2nm + 1)−connected piecewise-linear m−manifold (bounded or not), where mn ≥ 3. Then any element of πn(V) can be represented by a piecewise-linear imbedding of Sn in V.

(b) Let M be a (2nm + l)-connected closed piecewise-linear (m1)-manifold, where mn ≥ 3. Then two piecewise linear imbeddings of Sn−1 in V are isotopic if and only if they are homotopic.
