On R-Modified Crank-Nicholson Difference Schemes for the Source Identification Parabolic-Elliptic Problem

In the present paper, a space-dependent identification problem for parabolic-elliptic equations is investigated. The second order of accuracy r-modified Crank-Nicholson difference schemes for the numerical solution of the source identification parabolicelliptic problems are presented. Numerical results are given. © 2021 American Institute of Physics Inc.. All rights reserved.
