Uniform Sobolev estimates for non-trapping metrics
Abstract
We prove uniform Sobolev estimates $||u||_{L^{p'}} \leq C ||(Δ-α)u||_{L^{p}}$, where $p=2n/(n+2), p'=2n/(n-2)$, for the Laplacian $Δ$ on non-trapping asymptotically conic manifolds of dimension $n$. Here C is independent of $α$ which ranges over all complex numbers. This generalizes to non-constant coefficient Laplacians a result of Kenig-Ruiz-Sogge.
