On the ergodicity of the frame flow on even-dimensional manifolds

Mihajlo Cekić, Thibault Lefeuvre, Andrei Moroianu +1

It is known that the frame flow on a closed $n$-dimensional Riemannian manifold with negative sectional curvature is ergodic if $n$ is odd and $n\ne 7$. In this paper we study it…
