Lima, Å.; Roy, A. K. Some results on intersection properties of balls in complex Banach spaces. (English) Zbl 0645.46021 Stud. Math. 83, 37-45 (1986). Predual real \(L^ 1\)-spaces are characterized by the 4.2 intersection property. The structure of real spaces with the 3.2 intersection property and of real and complex spaces with the 4.3 intersection property is fairly well understood. In this paper we study complex spaces with the n.k. intersection property when \(n>k\geq 4\). We show that the 5.4. intersection property characterizes complex \(L^ 1\)-preduals, and that the \((2n+1).2n\). intersection property implies the almost \((2n+1).(2n- 1)\). intersection property in the complex case.
