摘要:

本文研究了在给定通常的 Cauchy 条件、齐次 Dirichlet 边界条件及积分超定条件的情况下,寻找具有变系数的时间分数阶一维扩散方程右端项的时间依赖乘子的反问题。超定条件采用对直接问题解在空间段上加权积分的形式,其中权重函数是方程右端项的空间依赖已知因子。这使得能够以显式形式构造反问题的解,并证明其在正则解类中的正确性。

英文摘要:

In this paper, we study the inverse problem of finding a time-dependent multiplier of the right-hand side of a time-fractional one-dimensional diffusion equation with variables coefficients in the case where the usual Cauchy, homogeneous Dirichlet boundary, and an integral overdetermination conditions are given. The overdetermination condition has the form of an integral with a weight over a spatial segment from the solution of the direct problem, in which the weight function is a spatially dependent known factor of the right-hand side of the equation. This made it possible to construct a solution to the inverse problem in explicit form and prove its correctness in the class of regular solutions
