We prove that the boundaries of the Milnor fibers of smoothings of non-isolated reduced complex surface singularities are graph manifolds. Moreover, we give a method, inspired by previous work of Némethi and Szilard, to compute associated plumbing graphs.

复杂曲面非孤立奇点的平滑拓扑

我们证明了非孤立简化复曲面奇点平滑的米尔诺纤维的边界是图流形。此外，我们在 Némethi 和 Szilard 先前工作的启发下，给出了一种方法来计算相关的管道图。
