A generalization of a theorem of Arrow, Barankin, and Blackwell. (English) Zbl 0652.90093
This paper presents a generalization of a known density theorem of K. J. Arrow, E. W. Barankin and D. Blackwell [Contrib. Theory of Games, II, Ann. Math. Studies 28, 87-91 (1953; Zbl 0050.142)]. This result is shown to hold even in a real normed space partially ordered by a Bishop-Phelps cone.
