Embeddings and the growth envelope of Besov spaces involving only slowly varying smoothness
We characterize local embeddings of Besov spaces B p,r involving only a slowly varying smoothness b into classical Lorentz spaces. These results are applied to establish sharp local embeddings of Besov spaces in question into Lorentz-Karamata spaces. As consequence of these results, we are able to determine growth envelopes of spaces B p,r and to show that we cannot describe all local embedding...
متن کاملSharp Embeddings of Besov Spaces with Logarithmic Smoothness
We prove sharp embeddings of Besov spaces B p,r (R ) with the classical smoothness σ and a logarithmic smoothness α into Lorentz-Zygmund spaces. Our results extend those with α = 0, which have been proved by D. E. Edmunds and H. Triebel. On page 88 of their paper (Math. Nachr. 207 (1999), 79–92) they have written: “Nevertheless a direct proof, avoiding the machinery of function spaces, would be...
متن کاملLocal Growth Envelopes of Besov Spaces of Generalized Smoothness
The concept of local growth envelope (ELGA, u) of the quasi-normed function space A is applied to the Besov spaces of generalized smoothness B p,q (Rn).
متن کاملApproximation and entropy numbers in Besov spaces of generalized smoothness
Let X and Y be Banach (or quasi-Banach) spaces and let T ∈ L(X,Y ) be a compact operator. In order to measure “the degree of compactness of T” one can use the asymptotic decay of the sequence of approximation numbers of T or the decay of the sequence of entropy numbers of T. In general, the behaviour of these sequences is quite different. However, as we shall show, under certain assumptions the...
متن کاملOptimal cubature in Besov spaces with dominating mixed smoothness on the unit square
We prove new optimal bounds for the error of numerical integration in bivariate Besov spaces with dominating mixed order r. The results essentially improve on the so far best known upper bound achieved by using cubature formulas taking points from a sparse grid. Motivated by Hinrichs’ observation that Hammersley type point sets provide optimal discrepancy estimates in Besov spaces with mixed sm...
