In this manuscript, the major objective is to investigate the existence and uniqueness (EU) of positive solutions for a general class of nonlinear fractional differential equation (FDE) with fractional differential and integral boundary conditions involving φp-Laplacian operator. To continue, we’ll utilize Green’s function to get the suggested FDE’s corresponding integral form. The existence findings are achieved by combining the Guo-Krasnosel’skii fixed point theorem with the features of the p-Laplacian operator. Additionally, Hyers-Ulam (HU) stability is also examined. Further, an example is presented to illustrate the effectiveness.
