The estimates of approximations classes in the Lorentz space

Closed access Metadata (CSL-JSON)
DOI 10.1063/1.4930453
Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Exact order estimates are obtained for the best orthogonal trigonometric approximations of the Nikol’skii-Besov classes of periodic functions of many variables in the Lorentz space with the mixed norm.
