文摘In this paper, we introduce the definition of generalized Day-James space on Rn (n 〉 2) and give a characterization of it, which extend some known results. In addition, we provide a sufficient and necessary condition for Day-James space, which reappeared Day's construction for any two-dimensional normed space to make Birkhoff orthogonality symmetry.
