Positively curved 7-dimensional manifolds
Fabio Podesta, Luigi Verdiani
We deal with seven dimensional compact Riemannian manifolds of positive curvature which admit a cohomogeneity one action by a compact Lie group G. We prove that the manifold is dif…

Totally geodesic orbits of isometries
Fabio Podesta, Luigi Verdiani
We study cohomogeneity one Riemannian manifolds and we establish some simple criterium to test when a singular orbit is totally geodesic. As an application, we classify compact, po…

Kahler manifolds with large isometry group
F. Podesta', A. Spiro
We investigate compact Kahler manifolds, which are acted on by a semisimple compact Lie group G of isometries with one hypersurface orbit. In case of ordinary action and projectabl…
