Abstract

In this work, we investigate the existence of the extremal solutions for a class of fractional partial differential equations with order $1<\alpha<2$ by upper and lower solution method. Using the theory of Hausdorff measure of noncompactness, a series of results about the solutions to such differential equations is obtained.

Keywords: fractional partial differential equation, mild solution, upper and lower solution method, Hausdorff measure of noncompactness
