A THEORY OF COBORDISM FOR NONSPHERICAL LINKS

We define an equivalence relation, called algebraic cobordism on the s et of bilinear forms over the integers. When n greater than or equal t o 3, we prove that two 2n - 1 dimensional, simple fibered links are co bordant if and only if they have algebraically cobordant Seifert forms . As an algebraic link is a simple fibered link, our criterion for cob ordism allows us to study isolated singularities of complex hypersurfa ces up to cobordism.
