利用DPW方法在三维空间中构造了以r3、s3和h3为形式的恒定平均曲率(CMC)泡面。我们证明了s3和h3中的泡子具有类似于r3中的泡子的性质。特别地,我们给出了在所有三种空间形式下的显式参数化,并证明了在所有三种空间形式下平行CMC曲面与原始气泡是一致的。此外,我们证明了通过DPW方法构造的曲面与Bianchi的曲面相同
We construct constant mean curvature (CMC) bubbleton surfaces in the three-dimensional space forms R 3 , S 3 and H 3 using the DPW method. We show that bubbletons in S 3 and H 3 have properties analogous to the properties of bubbletons inR 3 . In particular, we give explicit parametrizations in all three space forms, and we show that the parallel CMC surface is congruent to the original bubbleton in all three space forms. Furthermore, we prove that the construction here via the DPW method gives the same surfaces as Bianchi’s
