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.
One of the most common and effective methods of solving homogeneous problems of mathematical physics is the Fourier method or the method of separating variables.As you know, the main idea of this method is that the solution of the initial problem is reduced to the solution of auxiliary problems for equations with fewer independent variables.In particular, if the given equation contains 2 independent variables, the auxiliary problems will be dependent on one variable.
