%0 Journal Article %A Cobos Díaz, Fernando %A Fernández Besoy, Blanca %T The equivalence theorem for logarithmic interpolation spaces in the quasi-Banach case %D 2020 %@ 0232-2064 %U https://hdl.handle.net/20.500.14352/6070 %X We study the description by means of the J-functional of logarithmic interpolation spaces (A0, A1) 1, q, A in the category of the p-normed quasi-Banach couples (0 < p ≤ 1). When (A0, A1) is a Banach couple, it is known that the description changes depending on the relationship between q and A. In our more general setting, the parameter p also has an important role as the results show. %~
