设X是巴拿赫空间,研究高继的几个常数E(t,X),e(t,X),F(t,X),f(t,X)的几何性质,其中包括它的上下界和它与其它一些经典常数的关系.最后给出了蕴含正规结构的一些充分条件。
Let X be a Banach Space, some properties concerning Gao' s parameters E(t,X), e( t, X), F(t,X), f(t,X), including upper and lower bounds as well as relationship between some well known parameters and these parameters, are studied. Some sufficient conditions for the uniformly normal structure are presented.
