In our recent paper [Compact and continuous embeddings of logarithmic Bessel potential spaces. Studia Math. 168 (2005), 229 – 250] we have proved an embedding of a logarithmic Bessel potential space with order of smoothness σ less than one into a space of λ(·)-Hölder-continuous functions. We show that such an embedding is not compact and that it is sharp.
