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

In this paper, we will discuss a comparison result for solutions to the Cauchy problems for two stochastic differential equations with delay.On this subject number of authors have obtained their comparison results.We deal with the Cauchy problems for two integro-differential equations.Except transient-(or drift-) and diffusion coefficients our equations include also one integrodifferential term.Basic difference of our case from the case of all earlier investigated problems is presence of this term.We introduce a concept of solutions to our problems and prove the comparison theorem for them.According to our result under certain assumptions on coefficients of equations under consideration, their solutions depend on the transient-coefficients in a monotone way.
