STABILITY ANALYSIS AND NUMERICAL IMPLEMENTATION OF THE THIRD-ORDER FRACTIONAL PARTIAL DIFFERENTIAL EQUATION BASED ON THE CAPUTO FRACTIONAL DERIVATIVE

This paper examines a third-order fractional partial differential equation (FPDE) in the Caputo sense. The Theta difference method (TDM) is utilized to investigate the problem, and a first-order difference scheme is developed. Stability estimates are obtained by applying the Von Neumann analysis method. A test problem is presented as an application, and numerical results are obtained using Matlab software. Error estimates, as well as exact and approximate solutions are presented in a data analysis table. The simulation results are shown through error analysis tables and figures.
