Interpolation of weighted Sobolev spaces [PDF]

open access: yesJournal of Functional Analysis, 2019
In this work we present a newly developed study of the interpolation of weighted Sobolev spaces by the complex method. We show that in some cases, one can obtain an analogue of the famous Stein-Weiss theorem for weighted $L^{p}$ spaces. We consider an example which gives some indication that this may not be possible in all cases.

Weighted Sobolev Spaces on Curves [PDF]

open access: yesJournal of Approximation Theory, 2002
45 pages, no figures.-- MSC1987 codes: 41A10, 46E35, 46G10. MR#: MR1934626 (2003j:46038) Zbl#: Zbl 1019.46026 In this paper we present a definition of weighted Sobolev spaces on curves and find general conditions under which the spaces are complete for non-closed compact curves. We also prove the density of the polynomials in these spaces and, finally,

Weighted Variable Sobolev Spaces and Capacity [PDF]

open access: yesJournal of Function Spaces and Applications, 2012
We define weighted variable Sobolev capacity and discuss properties of capacity in the space 𝑊1,𝑝(⋅)(ℝ𝑛,𝑤). We investigate the role of capacity in the pointwise definition of functions in this space if the Hardy-Littlewood maximal operator is bounded on ...

Weighted Sobolev spaces: Markov-type inequalities and duality [PDF]

open access: yesBulletin of Mathematical Sciences, 2017
Weighted Sobolev spaces play a main role in the study of Sobolev orthogonal polynomials. The aim of this paper is to prove several important properties of weighted Sobolev spaces: separability, reflexivity, uniform convexity, duality and Markov-type ...

A new approach to weighted Sobolev spaces. [PDF]

open access: yesMon Hefte Math
Abstract We present in this paper a new way to define weighted Sobolev spaces when the weight functions are arbitrary small. This new approach can replace the old one consisting in modifying the domain by removing the set of points where at least one of the weight functions is very small.

On the trace space of a Sobolev space with a radial weight [PDF]

open access: yesJournal of Function Spaces and Applications, 2008
Our concern in this paper lies with trace spaces for weighted Sobolev spaces, when the weight is a power of the distance to a point at the boundary. For a large range of powers we give a full description of the trace space.

Traces of multipliers in pairs of weighted Sobolev spaces [PDF]

open access: yesJournal of Function Spaces and Applications, 2005
We prove that the pointwise multipliers acting in a pair of fractional Sobolev spaces form the space of boundary traces of multipliers in a pair of weighted Sobolev space of functions in a domain.
