en عمومى General پژوهشي Research paper <div style="text-align: justify;">In this work, the inverse quasi-linear pseudo-parabolic problem was investigated. We demonstrated the solution by the Fourier approximation. The inverse problem was first examined by linearizing and then used implicit finite difference schema for the numerical solution.</div> Pseudo-parabolic problem, Fourier method, Nonlocal(periodic) boundary condition, Implicit method. 193 209 http://ijmsi.ir/browse.php?a_code=A-10-3834-2&slc_lang=en&sid=1 Irem Baglan isakinc@kocaeli.edu.tr 100319475328460010656 100319475328460010656 No Department of Mathematics, Kocaeli University, Kocaeli 41380, Turkey Fatma Kanca fatma.kanca@fbu.edu.tr 100319475328460010657 100319475328460010657 No Department of Computer Engineering, Fenerbahce University, Istanbul, Turkey Vishnu Narayan Mishra Mishra vishnunarayanmishra@gmail.com 100319475328460010658 100319475328460010658 Yes Department of Mathematics, Indira Gandhi National Tribal University, Lalpur, Amarkantak, Anuppur, Madhya Pradesh 484 887, India
