【摘要】:在Banach空间X中引入了一个新的几何常数C_z~((p))(X),称为广义的Zbaganu常数。计算了该常数在任何Banach空间X中的上下界估计值。同时,给出了X是一致非方的等价条件,并讨论了C_z~((p))(X)常数与James常数之间的关系。最后将C_z~((p))(X)常数与不动点性质建立联系。
[Abstract]:In this paper, a new geometric constant, CZS, is introduced into Banach space X, which is called generalized Zbaganu constant. The upper and lower bounds of the constant in any Banach space X are calculated. At the same time, we give the equivalent conditions for X to be uniformly nonsquare, and discuss the relation between the James constant and the C _ S _ S _ T _ X) constant. Finally, the relation between the C _ ZH _ T _ (X) constant and the fixed point property is established.
