The Poisson equation on Riemannian manifolds with a weighted PoincarÃ Â© inequality at infinity. Monticelli, Dario
We prove an existence result for the Poisson equation on non-compact Riemannian manifolds satisfying a weighted Poincar\'e inequality outside a compact set. Our result applies to a large class of manifolds including, for instance, all non-parabolic manifolds with minimal positive Green's function vanishing at infinity. On the source function we assume a sharp pointwise decay depending on the weight appearing in the Poincar\'e inequality and on the behavior of the Ricci curvature at infinity. We do not require any curvature or spectral assumptions on the manifold. This result is a joint work with G. Catino and F. Punzo (Politecnico di Milano).
