We prove that the manifold of non-singular points of a stable real caustic germ of type and the manifolds of points of transversal intersection of its smooth branches consist only of contractible connected components. We also calculate the number of these components.

在真正的焦散类型

我们证明了类型稳定实焦散的非奇异点流形及其光滑分支的横向交点的流形仅由可收缩的连通分量组成。我们还计算这些组件的数量。
