We prove uniform decay estimates at infinity for solutions 0 ≤ u ∈ Lp of the semilinear elliptic inequality ∆u + auσ + bu ≥ 0, a, b ≥ 0, σ ≥ 1, in the presence of a Sobolev inequality (with potential term).

Abstract

We prove uniform decay estimates at infinity for solutions 0 ≤ u ∈ Lp of the semilinear elliptic inequality ∆u + auσ + bu ≥ 0, a, b ≥ 0, σ ≥ 1, in the presence of a Sobolev inequality (with potential term). This gives a unified point of view in the investigation of different geometric questions. In particular, we present applications to the study of the topology at infinity of parallel mean curvature submanifolds, to the non-compact Yamabe problem, and to estimate the decay rate of the traceless Ricci tensor of conformally flat manifolds.
