Abstract: Integral conditions on the traceless Ricci tensor are used to characterize Euclidean and hyperbolic spaces among complete, locally conformally flat manifolds of constant scalar curvature. The main tools are vanishing-type results for $ L^{p}$-solutions of a large class of differential inequalities. Further applications of the technique are also given.
