Using the Laplace transform and homotopy perturbation, wefind a semi-analyticalsolution. Finally, we give some examples for illustration.enExistence and uniqueness of solutions to higher order fractional partial differential equations with purely integral conditionsExistence and uniqueness of solutions to higher order fractional partial differential equations with purely integral conditionsArticle
