摘要
本文证明了欧氏空间RN中的n-维(n>2)完备极小子流形,若其全纯量曲率小于(π/46^(1/2)n,则必是n-维平面.此结论改进了文[2,6]中的结果.
In this paper, the author proves that: Let M be an n-dimensional (n > 2) complete minimal submanifold M in RN with ‖A‖n < ,where A stands for the second fundamental form of M, must be an n-dimensional plane, and generalizes the results in [2] and [6].
