New (3+1)-dimensional conformable KdV equation and its analytical and numerical solutions

In this research, we used the Riccati equation approach to establish new exact solution sets for a new (3+1)-dimensional Korteweg-de Vries (KdV) equation, which is an enlarged version of the time-fractional Kadomtsev-Petviashvili equation. Additionally, using the Mathematica symbolic computation program, approximate solutions to the equation, applying the residual power series method (RPSM), have been obtained. A comparison table and various graphical representations have been presented to demonstrate the validity of the solutions. The numerical findings indicate the effectiveness of both approaches in finding exact and approximate solutions to nonlinear fractional differential equations.
