摘要:
本文首先介绍了定理在去掉了“是严格凸的和”两个条件仍然成立[1]。其后我们通过改变文献[1]中的空间类型，弱化了定理中的条件，得到在2-范空间和n-范空间结论仍然成立，并且使得文献[1]中定理2.1成为本文定理2.3的推论。In this paper, we introduce Benz theorem that is established without the condition “Y is strictly convex and ”. Then the main theorem holds mainly by changing the type of space in [1] and weaking the conditions of the theorem in 2-normed space and in n-normed space. And the theorem 2.1 in [1] can be used as the corollary of theorem 2.3 in this paper.
