对于3-球面中的任意两个链环,我们提供了一个稳定映射f从3-球面到欧几里得平面的可视化构造,使得f没有尖点,f的确定(分别为不定)折叠点集与给定的第一个(分别为第二个)链环同痕,并且f不具有某种类型的奇异纤维。此外,通过将目标空间设为2-球面,我们对任意3-流形也获得了类似的结果。
英文摘要
For any two links in the $3$-sphere, we provide a visual construction of a stable map $f$ from the $3$-sphere to the Euclidean plane such that $f$ has no cusp points, the set of definite (resp. indefinite) fold points of $f$ is isotopic to the first (resp. second) given link, and $f$ does not have a certain type of singular fibers. Moreover, we obtain a similar result for any $3$-manifold by setting the target space to the $2$-sphere.
