摘要:
The subject of this paper is the explicit momentum construction of complete Einstein metrics by ODE methods. Using the Calabi ansatz, further generalized by Hwang-Singer, we show that there are non-trivial complete conformally Kahler-Einstein metrics on certain Hermitian holomorphic vector bundles and their subbundles over complete Kahler-Einstein manifolds. In special cases, we give the explicit expressions of these metrics. These examples show that there are a compact Kahler manifold M and its subvariety N whose codimension is greater than 1 such that there is a complete conformally Kahler-Einstein metric on M-N.
