摘要
We determine the associate space of the logarithmic interpolation space (X-0,X-1)(1,)q(,A) where X-0 and X-1 are Banach function spaces over a sigma-finite measure space (Omega, mu). Particularizing the results for the case of the couple (L-1, L-infinity) over a non-atomic measure space, we recover results of Opic and Pick on associate spaces of generalized Lorentz-Zygmund spaces L-(infinity,L-q;A). We also establish the corresponding results for sequence spaces.
