摘要
In this paper, we prove a Talenti-type comparison theorem for the p-Laplacian with Dirichlet boundary conditions on open subsets of a normalized RCD(K, K, N ) space with K > 0 and N E (1 infinity). The obtained Talenti-type comparison theorem is sharp, rigid and stable with respect to measured Gromov-Hausdorff topology. As an application of such Talenti-type comparison, we establish a sharp and rigid reverse H & ouml;lder inequality for first eigenfunctions of the p-Laplacian and a related quantitative stability result.
