摘      要：We consider Einstein-Weyl gravity with a minimally coupled scalar field in four dimensional *** the minimal geometric deformation(MGD)approach,we split the highly nonlinear coupled field equations into two subsystems that describe the background geometry and scalar field source,*** considering the Schwarzschild-AdS metric as background geometry,we derive analytical approximate solutions of the scalar field and deformation metric functions using the homotopy analysis method(HAM),providing their analytical approximations to fourth ***,we discuss the accuracy of the analytical approximations,showing they are sufficiently accurate throughout the exterior spacetime.
