In this paper, we study the asymptotic behavior of the energy densities of harmonic maps, exponentially harmonic functions and positive p-harmonic functions at infinity of a Riemannian manifold with asymptotically non-negative curvature. We prove that the energy densities of bounded harmonic maps, exponentially harmonic functions and positive p-harmonic functions all vanish at infinity.
Keywords: asymptotically non-negative Ricci curvature; exponentially harmonic function; harmonic map; positive p-harmonic function; gradient estimate
