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 consider an inverse problem on recovering the right-hand side of a fractional pseudo-parabolic equation with an involution operator.The major obstacle for considering the inverse problems is related with the well-posedness of the problem.Inverse problems are often ill-posed.For example, the inverse heat equation, deducing a previous distribution of temperature from final data, is not well-posed since the solution is highly sensitive to variations in the final data.The advantage of this paper is two-fold.On the one hand, we investigate the solvability of the direct problem and prove the solvability to this problem.On the other hand, we study the inverse problem based on this direct problem and prove the solvability results in this problem, too.First, we investigate the Cauchy problem for the time-fractional pseudo-parabolic equation with the involution operator, and secondly, we consider the inverse problem on recovering the right-hand side from an overdetermined final condition and prove that it is solvable.To achieve our goals, we use methods corresponding to the different areas of mathematics such as the theory of partial differential equations, mathematical physics, and functional analysis.In particular, we use the ℒ-Fourier analysis method to establish the existence and uniqueness of solutions to this problem on the Sobolev space.The classical and generalized solutions of the inverse problem are studied.
