Abstract

We prove that geodesic balls centered at some base point are isoperimetric in the real hyperbolic space HRnH_{\mathbb R}^n endowed with a smooth, radial, strictly log-convex density on the volume and perimeter. This is an analogue of the result by G. R. Chambers for log-convex densities on Rn\mathbb R^n. As an application we prove that in any rank one symmetric space of non-compact type, geodesic balls are isoperimetric in a class of sets enjoying a suitable notion of radial symmetry.
