Uniform convexity is well characterized in Orlicz spaces for both the Luxemburg and Orlicz norms [2], [3], [4] and in Besicovitch-Orlicz spaces of almost periodic functions for the Luxemburg norm [7]. The existence problem of the projection operator on closed convex subsets was considered in [5] in the case of Orlicz spaces, and in [8] in the case of Besicovitch-Orlicz space of almost periodic functions. In this paper we characterize the uniform convexity property in the Weyl-Orlicz spaces of almost periodic functions (W^a.p.) under the Luxemburg norm. Next this result is used to state the existence of the projection operator on complete convex subsets of W^a.p.

Abstract. In [2], T.R. Hillmann investigated some structural and topo-logical properties of the Besicovitch-Orlicz space (and others like as the Stepanoff and Weyl-Orlicz spaces) and his subspaces of almost periodic functions. In [3], we characterized the strict and uniform convexity of this space. In this paper, the strict convexity property is characterized in the Weyl-Orlicz space of almost periodic functions
