TY - JOUR TI - Approximate analytical solution for Phi-four equation with He’s fractal derivative AU - Deng Shuxian AU - Ge Xinxin JN - Thermal Science PY - 2021 VL - 25 IS - 3 SP - 2369 EP - 2375 PT - Article AB - This paper, for the first time ever, proposes a Laplace-like integral transform, which is called as He-Laplace transform, its basic properties are elucidated. The homotopy perturbation method coupled with this new transform becomes much effective in solving fractal differential equations. Phi-four equation with He’s derivative is used as an example to reveal the main merits of the present technology.
