秩二黎曼流形的余维二形变的分类

Classification of codimension two deformations of rank two Riemannian manifolds

Luis A. Florit, Guilherme M. de Freitas

摘要:

本文的目的是通过描述余维为2的二秩欧氏子流形的变形的模空间来封闭其局部变形问题。在这个过程中,我们提供了一个明确的简单表示这些子流形,一个结果的独立利益,其应用。我们还确定哪些变形是真正的和诚实的,使我们能够找到第一个已知的例子诚实的局部变形秩2子流形的余维2。此外,我们研究这些子流形承认等距浸入作为欧氏超曲面,一个属性,引起了几个应用的Sbrana-Cartan理论的变形欧氏超曲面。

英文摘要:

The purpose of this work is to close the local deformation problem of rank two Euclidean submanifolds in codimension two by describing their moduli space of deformations. In the process, we provide an explicit simple representation of these submanifolds, a result of independent interest by its applications. We also determine which deformations are genuine and honest, allowing us to find the first known examples of honestly locally deformable rank two submanifolds in codimension two. In addition, we study which of these submanifolds admit isometric immersions as Euclidean hypersurfaces, a property that gives rise to several applications to the Sbrana-Cartan theory of deformable Euclidean hypersurfaces.
