Abstract:
For any 3-manifold and any nonnegative integer , we give here examples of metrics on M each of which has a sequence of embedded minimal surfaces of genus and without Morse index bounds. On any spherical space form we construct such a metric with positive scalar curvature. More generally we construct such a metric with (and such surfaces) on any 3-manifold which carries a metric with .
