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

Some integral estimates on the cones of functions with the monotonicity conditionsIn this paper we obtain estimates for the integrals of monotone functions arising in the study of the covering of various cones of functions with monotonicity conditions.We apply the method of covering of the cones with the help of generalized Hardy operator.Sharp conditions are found on the kernels of representations for the validity of given estimates on the cones.The proofs are based on the reduction of integral estimates on the cones of monotone functions to ones on the family of characteristic functions of intervals.The obtained results can be used in finding the condition for the mutual covering of cones associated with decreasing rearrangement of the generalized Bessel and Riesz potentials.
