摘要:Riesz角度μ2(x)是Banach格空间中一个重要的几何常数,其与空间的不动点性质密切相关。研究了赋Luxemburg范数的Orlicz序列空间的M-常数和赋Luxemburg范数的Orlicz函数空间的M-常数,并在此基础上还给出了EΦ具有弱不动点性质的判别准则。

Abstract:Riesz angle μ2(x) is an important geometric constant in Banach lattice spaces, which is closely related to the fixed point properties of spaces. In this paper, the M-constants of Orlicz function spaces and Orlicz sequence spaces equipped with Luxemburg norm are obtained. On this basis, a criteria for EΦhas weak fixed point property was also given.
Keywords:M-constants; Orlicz spaces; Luxemburg norm; Riesz angles
