Abstract: In this article, we study Kähler metrics on a certain line bundle over some compact Kähler manifolds to find complete Kähler metrics with positive holomorphic sectional (or bisectional) curvatures. Thus, we apply a strategy to a famous Yau conjecture with a co-homogeneity one geometry.

Key words: Kähler Metrics, complete Riemannian metrics, open complex manifolds, holomorphic bisectional curvature, $C^*$ bundle, almost homogeneous manifolds
