The HPTM is a combined form of the Laplace transform, the homotopy perturbation method, and He’s polynomials. The nonlinear terms can be easily handled by the use of He’s polynomials. The proposed scheme finds the solutions without any discretization or restrictive assumptions and is free from round-off errors and therefore, reduces the numerical computations to a great extent. The speed of convergence of the method is based on a rapidly convergent series with easily computable components. The fractional derivatives are described here in the Caputo sense. Numerical results show that the HPTM is easy to implement and accurate when applied to time- fractional system of partial differential equations..
