“…RPSM method have been used by several authors in various fields, such as BoussinesqâBurgers equations [16], fractional diffusion equations [14], fuzzy differential equations [1], fractional Burger types equations [13], timeâfractional FokkerâPlanck equations [20], time fractional nonlinear coupled BoussinesqâBurgers equations [15], nonlinear fractional KdVâBurgers equation [6], higher order initial value problems [2], for linear and nonlinear LaneâEmden equations [3], system of multipantograph differential equations [12], system of Fredhlom integral equations [11], time fractional WhithamâBroerâKaup equations [19]], time fractional nonlinear gas dynamics equations [18], and is used for time fractional model of vibration equation [8]. Modeling and analysis of fractalâfractional partial differential equations for application to reactionâdiffusion model [17] and analytic approximate solutions of diffusion equations arising in oil pollution have been studied [4].…”
