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

Abstract A problem of finding a bounded on the whole axis solution of a nonhomogeneous differential equation with a limit of zero matrix and a right-hand part bounded with a weight is investigated by the parameterization method. Necessary and sufficient conditions for the well-posedness of the considered problem are obtained in terms of a bilaterally infinite matrix of special structure.
