R^N中taut子流形的性质与例

A Property of Taut Submanifolds in R^N and an Example

给出了紧致taut子流形的一个性质，即它确实是由标准球面堆砌（buildup）而成的．本文也证明了某类近复子流形可taut嵌入到RN．

In this note, we give a property of compact taut submainifolds in RN which shows that taut submanifolds are really built up by spheres. We also give an example of taut submanifold in RN.
