摘要: |
讨论Banach空间Xk-drop凸及局部k-drop凸的性质,给出X(局部)k-drop凸的充要条件,并利用该充要条件,证明若(X⊕Y)1为k-DC空间,则X,Y分别为k-DC空间. |

Abstract: |
We give the suffcient and necessary condition for Banach space to be (L)k-DC, by which it is proved that if (X⊕Y)1 is the space k-DC. |
Key words: k-drop convexity locally k-drop convexity affinely span |
