Efficient Computation of Laplace Residual Power Series with Explicit Coefficient Formulas

Abstract: The Residual Power Series Method (RPSM) provides a powerful framework for solving fractional differential equations. However, a significant computational bottleneck arises from the necessity of calculating the fractional derivatives of the residual function within the coefficient determination process. The Laplace Residual Power Series Method (LRPSM) partially addresses this by employing the Laplace transform. However, it introduces additional complexities and requires the computation of the residual error function at each iteration. This work presents a novel approach that directly derives explicit formulas for the coefficients, Bypassing the need for iterative residual error function calculations. This advancement significantly enhances the computational efficiency of the method compared to both RPS method and LRPS method.
