In this talk, we describe some monotonicity formulas holding along the level sets of suitable p–harmonic functions in asymptotically flat 3–manifolds with a single end, either with or without boundary, having nonnegative scalar curvature. Using such the formulas, we obtain a simple proof of the positive mass theorem and the Riemannian Penrose inequality. The results discussed are obtained by a collaboration with Virginia Agostiniani, Carlo Mantegazza and Lorenzo Mazzieri.
