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…
Immersions of surfaces in spin-manifolds with Higgs fields
Andrzej Derdzinski, Tadeusz Januszkiewicz
We define a `Higgs field' for a four-dimensional spin-manifold to be a smooth section of its positive half-spinor bundle, transverse to the zero section, and defined only up to…
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…
