Scalar curvature along Ebin geodesics

Christoph Böhm, Timothy Buttsworth, Brian Clarke

Let $M$ be a smooth, compact manifold and let $N_{μ}$ denote the set of Riemannian metrics on $M$ with smooth volume density $μ$ . For a given $g_{0} \in N_{μ}$ , we sho…

Non-compact Einstein manifolds with unimodular isometry group

Christoph Böhm, Ramiro A. Lafuente

We show that a negative Einstein manifold admitting a proper isometric action of a connected unimodular Lie group with compact, possibly singular, orbit space splits isometrically…
