Generalized Einstein manifolds

Journal of Geometry and Physics, 1995
The geometrization of physics, especially regarding the equations of electromagnetism and gravitation in general relativity, has been a vital problem of investigation for a long time. A. Einstein himself devoted the last several years of his life to realize this dream without success. However, taking grant of two axioms proposed by \textit{D. Hilbert} [

On Einstein four-manifolds

Journal of Geometry and Physics, 2004
Topological obstructions to the existence of Einstein metrics on a given compact and oriented 4-manifold were found by \textit{N. Hitchin} [J. Differ. Geom. 9, 435--441 (1974; Zbl 0281.53039)] and by \textit{M. J. Gursky} and \textit{C. LeBrun} [Ann. Global Anal. Geom. 17, No. 4, 315--328 (1999; Zbl 0967.53029)].

On Einstein Hermitian manifolds [PDF]

open access: possibleMonatshefte für Mathematik, 2007
We show that every compact Einstein Hermitian surface with constant *–scalar curvature is a Kahler surface. In contrast to the 4-dimensional case, it is shown that there exists a compact Einstein Hermitian (4n + 2)-dimensional manifold with constant *–scalar curvature which is not Kahler.
