对空间曲线上函数的简单奇点进行了分类。证明了它们的分支集具有与光滑流形和完全相交上的函数非常相似的性质:函数分支图的k(π,1)-定理是正确的,并且这个图和判别式都是Saito的自由因子。
Simple singularities of functions on space curves are classified. It is shown that their bifurcation sets have properties very similar to those of functions on smooth manifolds and complete intersections: the k(π, 1)‐theorem for the bifurcation diagram of functions is true, and both this diagram and the discriminant are Saito's free divisors.
