DOI: 10.1002/mana.201700240

Abstract: Geodesic balls in a simply connected space forms $\mathbb{S}^n$, $\mathbb{R}^{n}$ or $\mathbb{H}^{n}$ are distinguished manifolds for comparison in bounded Riemannian geometry. In this paper we show that they have the maximum possible boundary volume among… read more here.

Published in 2018 at "Annals of Global Analysis and Geometry"

DOI: 10.1007/s10455-018-9606-4

Abstract: In this paper, we study the critical metrics for quadratic curvature functionals involving the Ricci curvature and scalar curvature in the space of Riemannian metrics with unit volume. For these functionals, Einstein metrics are always… read more here.

Published in 2019 at "Israel Journal of Mathematics"

DOI: 10.1007/s11856-019-1930-2

Abstract: We provide an isoperimetric inequality for critical metrics of the volume functional with nonnegative scalar curvature on compact manifolds with boundary. In addition, we establish a Weitzenb\"ock type formula for critical metrics of the volume… read more here.
