%0 Journal Article %A Cobos Díaz, Fernando %A Kühn, Thomas %T Extrapolation estimates for entropy numbers %D 2012 %@ 0022-1236 %U https://hdl.handle.net/20.500.14352/42443 %X We establish abstract extrapolation results for entropy numbers of operators in Banach spaces. The results apply to extrapolation in the source spaces and also in the target spaces. As an illustration of the abstract results, applications to limiting Sobolev embeddings are given. %~
