Isoparametric foliations and bounded geometry

Manuel Krannich, Alexander Lytchak, Marco Radeschi

We prove that there are only finitely many isoparametrically foliated closed connected Riemannian manifolds with bounded geometry, fixed dimension , and finite fundamental…

Riemannian foliations on CROSSes

Marco Radeschi, Lorenzo Scoffone, Michael Wiemeler

We classify Riemannian foliations of closed manifolds homotopy equivalent to CROSSes.

On the Rational Hyperbolicity problem

Ricardo Mendes, Alessandro Minuzzo, Marco Radeschi

We prove that a compact simply connected manifold with a variationally complete -action satisfying certain mild conditions (e.g. trivial principal isotropy, or simply connec…

Manifold submetries from compact homogeneous spaces

Samuel Lin, Ricardo A. E. Mendes, Marco Radeschi

We show that singular Riemannian foliations, or, more generally, manifold submetries, defined on a compact normal homogeneous space, have algebraic nature. Moreover, in this case t…

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 -manifolds from their quotients

Elahe Khalili Samani, Marco Radeschi

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