我们在整数上的双线性形式集上定义了一个等价关系,称为代数协边。当且仅当两个 2n-1 维简单光纤链路具有代数协调 Seifert 形式时,它们才是协调的。由于代数链接是简单的纤维链接,因此我们的共边标准使我们能够研究复杂超曲面的孤立奇点直至共边。
We define an equivalence relation, called algebraic cobordism, on the set of bilinear forms over the integers. When, we prove that two 2n- 1 dimensional, simple fibered links are cobordant if and only if they have algebraically cobordant Seifert forms. As an algebraic link is a simple fibered link, our criterion for cobordism allows us to study isolated singularities of complex hypersurfaces up to cobordism.
