Inclusion indices of quasi-Banach spaces. (English) Zbl 1179.46026
Summary: We investigate inclusion indices for quasi-Banach spaces. First, we consider the case of function spaces on \([0,1]\), then the sequence case and, finally, we develop an abstract approach dealing with indices defined by the real interpolation scale generated by a quasi-Banach couple.
