Rational ellipticity of $G$-manifolds from their quotients

Abstract

We prove that if a compact, simply connected Riemannian GG-manifold MM has orbit space M/GM/G isometric to some other quotient N/HN/H with NN having zero topological entropy, then MM is rationally elliptic. This result, which generalizes most conditions on rational ellipticity, is a particular case of a more general result involving manifold submetries.
