Wavelet Solutions for the Time-Fractional Phi-Four \((\phi ^4)\) Equation with Caputo Derivatives
摘要
The time-fractional Phi-Four \((\phi ^4)\) equation (TFPFE) is a prominent nonlinear model that arises in diverse fields, including quantum field theory, statistical mechanics, and phase transition studies. Its fractional form incorporates memory effects, capturing the complex temporal evolution seen in real-world systems. In this research, we propose a novel approach for solving the TFPFE by using Hermite Wavelet methods (HWM) in combination with the Caputo fractional derivative (CFD). The CFD is selected for its ability to handle physical initial conditions, making it highly suitable for modeling dynamic systems. A numerical investigation is presented to support the correctness and reliability of the approach. To illustrate the suitability and robustness of the recommended method, absolute errors are calculated for each problem. We compare our method with other popular approaches, like Yang transforms decomposition method (YTDM), Yang homotopy perturbation transform method (YHPM) and q-homotopy analysis transform method (q-HATM), and found that it is more accurate and computationally efficient.
