Abstract:Abstract:Nearly uniform noncreasy is a important property in Banach spaces. In this paper we introduce a new geometric property, which is called sub nearly uniformly convex property. It implies that Banach spaces have weak fixed point property for nonexpansive mappings. The necessary and sufficient condition for the Orlicz sequence space with Luxemburg norm to be sub nearly uniformly convex is given.
