Abstract : We describe the asymptotic behavior of functions of the Royden $p$-algebra in terms of $p$-extremal length. We also prove that each bounded $\mathcal A$-harmonic function with finite energy on a complete Riemannian manifold is uniquely determined by the behavior of the function along $p$-almost every curve.
Keywords : $\mathcal A$-harmonic function, $p$-harmonic boundary, comparison principle, maximum principle, $p$-extremal length, $p$-almost every curve
