模型的Catlin多型与双全纯等价
The Catlin multitype and biholomorphic equivalence of models
摘要:
我们考虑一种替代方法的基本CR不变-卡特林多型。它适用于$\mathbbC^{n+1}$中的一般光滑超曲面,不一定是伪凸的。利用这种方法,我们证明了模型的双全纯等价性,并给出了不同模型之间的双全纯映射的一个明确的描述。本文给出了一种计算多型的构造性有限算法。这些结果是理解有限Catlin多型Levi退化超曲面的局部双全纯等价性的必要步骤。
英文摘要:
We consider an alternative approach to a fundamental CR invariant - the Catlin multitype. It is applied to a general smooth hypersurface in $\mathbbC^{n+1}$, not necessarily pseudoconvex. Using this approach, we prove biholomorphic equivalence of models, and give an explicit description of biholomorphisms between different models. A constructive finite algorithm for computing the multitype is described. The results can be viewed a necessary step in understanding local biholomorphic equivalence of Levi degenerate hypersurfaces of finite Catlin multitype.
