| contents | In this paper, we study several types of geometric problems related to the Ricci curvature on noncompact complex manifolds, such as the existence of Kähler-Einstein metrics on complete Kähler manifolds with negative Ricci curvature, which can be seen as an improvement of the main theorem in Cheng-Yau [4]; the existence of canonical Hermitian metrics with prescribed Ricci curvature on complete Hermitian manifolds, which can be regarded as noncompact versions of the Gauduchon conjecture on certain complete complex surfaces. Our method can also be used to construct Hesse-Einstein metrics in affine differential geometry. |
