On the real interpolation methods of Banach \((n+1)\)-tuples. (English) Zbl 0910.46057
Summary: The Peetre’s \(K\)- and \(J\)-methods of interpolation of Banach couples are extended to \(n+1\), \(n\geq 2\) Banach spaces. In particular cases, we obtain the results from [the authors, N. Cofan and P. Gavruta [Semin. Oper. Liniari Anal. Armonica, Univ. Timişoara 1 (1988; Zbl 0686.46046)] and [G. Sparr, Ann. Mat. Pura Appl. IV. Ser. 99, 247-316 (1974; Zbl 0282.46022)].
