Mar 7, 2011 at 14:07 comment added Henri A theorem of Aubin-Yau says that any compact Kähler manifold with $c_1(X)$ negative or zero (as cohomology class) is Kähler-Einstein, in the sense that there exists $\omega$ a Kähler metric satisfyinf respectively $Ric(\omega)=-\omega$ (resp. $Ric(\omega)=0$). In the case where $c_1(X)>0$, it is not always true, but we know some examples (well-chosen weigted spaces e.g).
