RT Journal Article T1 Extrapolation results of Lions-Peetre type A1 Cobos, Fernando A1 Kühn, Thomas AB We establish compactness results for extrapolation constructions which correspond to the well-known Lions-Peetre compactness theorems of interpolation theory. Applications are given to compactness of certain limiting Sobolev embeddings.
