We present conditions which are necessary and sufficient for compact embeddings of Bessel potential spaces H σ X(IRn ), modelled upon a rearrangement-invariant Banach function spaces X(IRn ), into generalized Hölder spaces involving k-modulus of smoothness. To this end, we derive a characterization of compact subsets of generalized Hölder spaces. We apply our results to the case when X(IRn ) is a Lorentz-Karamata space Lp,q;b(IRn ). Applications cover both superlimiting and limiting cases.
