A Myers-type theorem and compact Ricci solitons
Andrzej Derdzinski
Let the Ricci curvature of a compact Riemannian manifold be greater, at every point, than the Lie derivative of the metric with respect to some fixed smooth vector field. It is sho…
A moduli curve for compact conformally-Einstein Kähler manifolds
A. Derdzinski, G. Maschler
We classify quadruples in which is a compact Kähler manifold of complex dimension with a nonconstant function on such that the conformally related…
Curvature-homogeneous indefinite Einstein metrics in dimension four: the diagonalizable case
Andrzej Derdzinski
We classify those curvature-homogeneous Einstein four-manifolds, of all metric signatures, which have a complex-diagonalizable curvature operator. They all turn out to be locally h…
Special Kähler-Ricci potentials on compact Kähler manifolds
A. Derdzinski, G. Maschler
A special Kähler-Ricci potential on a Kähler manifold is any nonconstant function such that is a Killing vector field and, at every point with …
Local classification of conformally-Einstein Kähler metrics in higher dimensions
A. Derdzinski, G. Maschler
The requirement that a (non-Einstein) Kähler metric in any given complex dimension be almost-everywhere conformally Einstein turns out to be much more restrictive, even local…
