Title: | Spaces of Bessel-potential type and embeddings: the super-limiting case | Authors: | Neves, Júlio S. | Issue Date: | 2004 | Citation: | Mathematische Nachrichten. 265:1 (2004) 68-86 | Abstract: | We consider Bessel-potential spaces modelled upon Lorentz-Karamata spaces and establish embedding theorems in the super-limiting case. In addition, we refine a result due to Triebel, in the context of Bessel-potential spaces, itself an improvement of the Brézis-Wainger result (super-limiting case) about the ldquoalmost Lipschitz continuityrdquo of elements of H1+n/pp (ℝn). These results improve and extend results due to Edmunds, Gurka and Opic in the context of logarithmic Bessel potential spaces. We also give examples of embeddings of Besselpotential type spaces which are not of logarithmic type. (© 2004 WILEY-VCH Verlag GmbH & Co.
