Positive intermediate Ricci curvature on cohomogeneity one manifolds in low dimensions

Elahe Khalili Samani, Lawrence Mouillé

We explore existence of invariant metrics with positive intermediate Ricci curvature on closed, low-dimensional cohomogeneity one manifolds. For a certain cohomogeneity one $\maths…

Positive curvature and rational ellipticity in cohomogeneity three

Elahe Khalili Samani, Marco Radeschi

We prove that a closed, simply connected, positively curved, cohomogeneity-three manifold whose quotient space has no boundary is rationally elliptic, thus providing a generalizati…

Rational ellipticity of $G$ -manifolds from their quotients

Elahe Khalili Samani, Marco Radeschi

We prove that if a compact, simply connected Riemannian $G$ -manifold $M$ has orbit space $M / G$ isometric to some other quotient $N / H$ with $N$ having zero topological entropy, then…

On the topology of leaves of singular Riemannian foliations

Marco Radeschi, Elahe Khalili Samani

In this paper, we establish a number of results about the topology of the leaves of a closed singular Riemannian foliation $(M,\fol)$. If $M$ is simply connected, we prove that the…
