摘要:

James与Schffer分别对赋范线性空间引入了不同的非方的定义. 赋Orlicz范数与赋Luxemburg范数的Orlicz-Bochner空间是非方的充分必要条件:LM(X)是非方的当且仅当X是非方的;L(M)(X)是非方的当且仅当M∈Δ2,且X是非方的. 

Abstract:

James and Schffer introduced two different definitions of nonsquare normed linear space respectively. In this paper, the sufficient and necessary conditions are given for the nonsquare OrliczBochner spaces endowed with Orlicz norm and Luxemburg norm. LM(X) is nonsquare if and only if X is nonsquare. L(M)(X) is nonsquare if and only if  M∈Δ2 and X is nonsquare. 

Key words:  Orlicz-Bochner space; nonsquare; Luxemburg norm; Orlicz norm
