摘要

给定任意（不一定相连的）组合有限图和任意具有第三个贝蒂数的紧凑光滑 6-manifold，我们在光滑度量中在配备上构造了一个校准的三维同源面积最小曲面，因此曲面的奇点集正是这个有限图的嵌入。此外，奇点集附近的校准形式是一种平滑扭曲的特殊拉格朗日形式。这些构造基于卡米洛-德莱利斯教授和罗伯特-布莱恩特教授一些未发表的观点。

Every finite graph arises as the singular set of a compact 3-D calibrated area minimizing surface

Given any (not necessarily connected) combinatorial finite graph and any compact smooth 6-manifold $M^{6}$ with the third Betti number $b_{3} \neq 0$ , we construct a calibrated 3-dimensional homologically area minimizing surface on $M$ equipped in a smooth metric $g$ , so that the singular set of the surface is precisely an embedding of this finite graph. Moreover, the calibration form near the singular set is a smoothly $G L (6, R)$ twisted special Lagrangian form. The constructions are based on some unpublished ideas of Professor Camillo De Lellis and Professor Robert Bryant.
