Stably irreducible surfaces in S4

Charles Livingston

Vol. 116 (1985), No. 1, 77–84
Abstract

It is shown by example that there are embedded surfaces in S4 which cannot be decomposed as the connected sum of a knotted surface of lower genus and an unknotted surface. In addition it is shown that there are distinct embeddings of surfaces into S4 such that the complements of the surfaces have the same fundamental groups. The results are generalized to a stable setting. All groups that appear are classical knot groups.
