| contents | This article investigates the genericity of ergodic probability measures for the geodesic flow on non-positively curved Riemannian manifolds. We demonstrate that the existence of an open isometric embedding of a product manifold with a factor isometric to $S^1$ implies that the closure of the set of ergodic measures does not encompass all invariant measures, thus the genericity of ergodic probability measures fails. Our findings notably provide an answer to an open question concerning a specific example of 3-manifold attributed to Heintze. |
