Global Green’s Function Estimates

Part of the International Mathematical Series book series (IMAT, volume 13)


Under certain conditions, we obtain global pointwise estimates for Neumann series associated with an integral operator with general quasimetric kernel. The estimates involve the first and second iterations of the original kernel. As a consequence we deduce sharp bilateral bounds of Green's function for the fractional Schrödinger operator (− Δ)α/2 −q with general attractive potential q ≥ 0 on the entire Euclidean space \(\mathbb{R}^n\) for 0 < α < n, or a bounded nontangentially accessible domain \(\Omega \subseteq \mathbb{R}^n \) for 0 < α ≤ 2, under a certain “smallness condition” on q. Most of our results are new even in the classical case α = 2.
