本文研究了黎曼流形在低余维中的嵌入问题。Nash和Kuiper的著名结果(Nash in Ann.Math.60:383-396,1954; Kuiper in Proc. Kon. Acad.湿了Amsterdam A 58:545-556,1955; Kuiper in Proc. Kon. Acad.湿了Amsterdam A 58:683-689,1955)说,余维1中的任何短嵌入都可以由C1等距嵌入一致地近似。由于Weyl问题中的经典刚性,这种说法显然对一般的C2嵌入不成立。事实上,鲍里索夫扩展后者的嵌入类C1,α与α>2/3(鲍里索夫在Vestn。列宁14(13):20-26,1959; Borisov in Vestn.列宁15(19):127-129,1960)。另一方面,他宣布在(鲍里索夫在Doklady 163:869-871,1965年),纳什-柯伊伯声明可以扩展到当地的C 1,α嵌入与α<(1+n+n 2)−1,其中n是维数的流形,提供的度量是解析的。随后证明的二维情况下出现在(鲍里索夫在西伯利亚。Mat. Zh. 45(1):25-61,2004)。本文对一般维数和一般度量给出了所有这些命题的解析证明。
In this paper we study the embedding of Riemannian manifolds in low codimension. The well-known result of Nash and Kuiper (Nash in Ann. Math. 60:383–396, 1954; Kuiper in Proc. Kon. Acad. Wet. Amsterdam A 58:545–556, 1955; Kuiper in Proc. Kon. Acad. Wet. Amsterdam A 58:683–689, 1955) says that any short embedding in codimension one can be uniformly approximated by C 1 isometric embeddings. This statement clearly cannot be true for C 2 embeddings in general, due to the classical rigidity in the Weyl problem. In fact Borisov extended the latter to embeddings of class C 1,α with α>2/3 in (Borisov in Vestn. Leningr. Univ. 14(13):20–26, 1959; Borisov in Vestn. Leningr. Univ. 15(19):127–129, 1960). On the other hand he announced in (Borisov in Doklady 163:869–871, 1965) that the Nash–Kuiper statement can be extended to local C 1,α embeddings with α<(1+n+n 2)−1, where n is the dimension of the manifold, provided the metric is analytic. Subsequently a proof of the 2-dimensional case appeared in (Borisov in Sib. Mat. Zh. 45(1):25–61, 2004). In this paper we provide analytic proofs of all these statements, for general dimension and general metric.
