Mixed norms and Sobolev type inequalities

V. I. Kolyada (2006)

Banach Center Publications

Similarity:

We study mixed norm spaces that arise in connection with embeddings of Sobolev and Besov spaces. We prove Sobolev type inequalities in terms of these mixed norms. Applying these results, we obtain optimal constants in embedding theorems for anisotropic Besov spaces. This gives an extension of the estimate proved by Bourgain, Brezis and Mironescu for isotropic Besov spaces.

Mixed 3-Sasakian structures and curvature

Angelo V. Caldarella, Anna Maria Pastore (2009)

Annales Polonici Mathematici

Similarity:

We deal with two classes of mixed metric 3-structures, namely the mixed 3-Sasakian structures and the mixed metric 3-contact structures. First, we study some properties of the curvature of mixed 3-Sasakian structures. Then we prove the identity between the class of mixed 3-Sasakian structures and the class of mixed metric 3-contact structures.
