Semin. Oper. Liniari Anal. Armonică, Univ. Timişoara 9, 15 p. (1985).
In this paper we extend the real interpolation methods (\(\theta\),p,K) and (\(\theta\),p,J) for quasi-normed Abelian groups to (f,p,K) and (f,p,J) methods, respectively. The theory developed is applied to interpolation of \(\ell^ f_ p(A)\) and \(L^ p\) spaces.
