Comparison results for solutions of Poisson equations with Robin boundary on complete Riemannian manifolds
Abstract
In this paper, by using Schwarz rearrangement and isoperimetric inequalities, we prove comparison results for the solutions of Poisson equations on complete Riemannian manifolds with Ric≥ (n-1), \, ≥ 0, which extends the results in ANT-Talenti-a. Furthermore, as applications of our comparison results, we obtain the Saint-Venant inequality and Bossel-Daners inequality for Robin Laplacian.
