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

We study the inverse problem for non-stationary system of magnetic hydrodynamics in which it is required to determine the velocity of the fluid $\vec{v}(x,t)$ , the magnetic tension $\vec{H}(x,t)$ , the pressure gradient $\nabla p(x,t)$ , but also the external forces $\vec{f}(x)$ and the current $\operatorname{rot}\vec{j}(x)$ . In this case, to the conditions constituting the direct problem are added additional conditions. The trace speed, the magnetic tension, and the pressure gradient in the final moment, time $t=T$ , are taken as additional information. The strong generalized solvability of the inverse problem in the two-dimensional case is proved.
