Abstract: Sobolev embeddings that are in a sense optimal, or nearly optimal, are typically noncompact. There are various quantities measuring "how bad" noncompactness of operators (e.g., of Sobolev embeddings) is, such as the ball measure of noncompactness or some so-called s-number. We will investigate some (nearly) optimal Sobolev embeddings from such a quantitative point of view.
