A Talenti-type comparison theorem for RCD(K, N) spaces and applications

Abstract:

We prove pointwise and L p -gradient comparison results for solutions to elliptic Dirichlet problems defined on open subsets of a (possibly non-smooth) space with positive Ricci curvature (more precisely of an RCD(K, N) metric measure space, with K > 0 and N ∈ (1, ∞)). The obtained Talenti-type comparison is sharp, rigid and stable with respect to L 2/measured-Gromov-Hausdorff topology; moreover it seems new even for smooth Riemannian manifolds. As applications of such Talenti-type comparison...
