我们发展了收缩复合体中的极小曲面理论,这是研究收缩复合体的有力工具。我们证明了平面极小曲面在收缩复杂几乎等距嵌入,并介绍了一个局部条件,平面,这意味着极小。我们还证明了极小曲面在其边界发生微小变形的情况下是稳定的。20F65、20F67、53C21
We develop the theory of minimal surfaces in systolic complexes, which is a powerful tool in studying systolic complexes. We prove that flat minimal surfaces in a systolic complex are almost isometrically embedded and introduce a local condition for flat surfaces which implies minimality. We also prove that minimal surfaces are stable under small deformations of their boundaries. 20F65, 20F67; 53C21
