【摘要】 本文研究Orlicz 空间的端点问题,给出了Orlicz 空间(L_M^*,‖·‖_M)及（L_M^*,‖·‖_M）的闭单位球中的某一点是端点的充要条件.从而导出了吴从忻给出的(L_M^*,‖·‖_M)是严格凸的充要条件.且指出(L_M^*,‖·‖_M)中的闭单位球必存在端.更多还原

【Abstract】 Some criteria of the extreme points on the closed unit sphere of Orlicz spaces(L_?^*,‖·‖_M)and（L_M^*,‖·‖_M）are obtained.A thcorem of Wu Cong-Xin on the stric-fly convexity of Orlicz space(L_M^*,‖·‖_M)is deduced as a corollary of our res-（?）lt.It is shown also that there always exist infintely many extreme points onthe closed unit sphere of(L_M^*,‖·‖_M).更多还原
