Removability of non-isolated singularities for Einstein metrics and RCD spaces

Gioacchino Antonelli, Gábor Székelyhidi

In this paper we establish removable singularities results for Einstein metrics and for metrics with Ricci curvature bounded below. Let $n \geq 2$ . On a closed $n$ -manifold, we show…

Universal Volume Growth Bounds from Positive Intermediate Curvature

Gioacchino Antonelli

Let $n, m$ be integers such that $n \geq 2$ and $0 \leq m \leq n - 2$ . Let $C_{m + 1}$ denote the $(m + 1)$ -intermediate curvature introduced by Brendle--Hirsch--Johne. We prove that there ar…

Spaces of metrics with positive spectral scalar curvature

Gioacchino Antonelli, Georg Frenck, Bernhard Hanke

Let $n \geq 2$ and let $M^{n}$ be a closed connected smooth manifold. Let $R^{γ} (M)$ be the space of smooth Riemannian metrics $g$ on $M$ for which the generalized conformal Laplace oper…

Rigidity and flexibility under spectral Ricci lower bounds and mean-convex boundary

Gioacchino Antonelli, Yangyang Li, Paul Sweeney

We study Riemannian manifolds $(M^{n}, g)$ with mean-convex boundary whose Ricci curvature is nonnegative in a spectral sense. Our first main result is a sharp spectral extension of a…
