嵌入曲面的均匀化

Uniformization of embedded surfaces

Neil Strickland

摘要:

设X是嵌入三维球面的亏格为2的闭曲面。然后X继承了一个度量和一个方向,这给出了一个殆复结构,它自动集成到一个真正的复结构,使X成为黎曼曲面。由此得出X共形同构于黎曼球面的分支覆盖,或者通过富克斯群的作用共形同构于单位圆盘的商。这些陈述背后的定理是重要的,众所周知的,并且有一个世纪的历史。尽管如此,我们认为,文献中没有任何例子可以明确的结构的一个重要部分。这本专著是一个部分成功的尝试,提供这样一个例子,从一个特定的表面X,有有趣的几何形状。所需的理论是令人惊讶的丰富,并支持大量的Maple代码,这是用于半形式化验证的许多证明,以及数值计算。

英文摘要:

Let X be a closed surface of genus two embedded in the 3-sphere. Then X inherits a metric and an orientation, which give an almost complex structure, which automatically integrates to a genuine complex structure, making X a Riemann surface. It follows that X is conformally isomorphic to a branched cover of the Riemann sphere, or to the quotient of the unit disc by the action of a Fuchsian group. The theorems behind these statements are important, well-known, and a century old. Nonetheless, we believe that the literature contains no examples where a significant fraction of the structure can be made explicit. This monograph is a partially successful attempt to provide such an example, starting with a particular surface X that has interesting geometry. The required theory is surprisingly rich, and is supported by a large body of Maple code, which is used for semi-formal verification of many proofs, as well as for numerical calculation.
