Abstract

The paper investigates the inverse problem of determining the unknown time-dependent source in the Cauchy problem for the diffusion equation with time-fractional derivatives with redefinition at the point x = 0. To solve the inverse problem

the fundamental solution of the diffusion equation with time-fractional derivatives is used. The inverse problem is reduced to an equivalent linear Volterra integral equation of the second kind. Using the method of successive approximations, we prove the existence and uniqueness of a solution to the problem under consideration. A stability estimate is also obtained.
