Interpolation of $$2^ n$$ Banach spaces with a function parameter. (English) Zbl 0669.46036
Semin. Oper. Liniari Anal. Armonică, Univ. Timişoara 5, 14 p. (1987).
Peetre’s K and J methods for interpolation with a function parameter are extended to the special case of 2$${}^ n$$ Banach spaces. An application to Lorentz spaces, with mixed norms, is given.
