Spaces of positive intermediate curvature metrics

Georg Frenck, Jan-Bernhard Kordaß

In this paper we study spaces of Riemannian metrics with lower bounds on intermediate curvatures. We show that the spaces of metrics of positive p-curvature and k-positive Ricci cu…

Bundles with even-dimensional spherical space form as fibers and fiberwise quarter pinched Riemannian metrics

Diego Corro, Karla Garcia, Martin Günther +1

Let $E$ be a smooth bundle with fiber an $n$ -dimensional real projective space $R P^{n}$ . We show that, if every fiber carries a positively curved pointwise strongly $1/4$ -pi…

Curvature bounds for regularized riemannian metrics

Daniel Luckhardt, Jan-Bernhard Kordaß

We investigate regularization of riemannian metrics by mollification. Assuming both-sided bounds on the Ricci tensor and a lower injectivity radius bound we obtain a uniform estima…
