摘要：
We discuss the local geometry in the vicinity of a sphere CP1 embedded with a negative normal bundle. We show that the behavior of the Kahler potential near a sphere embedded with a given normal bundle can be determined using the adjunction formula. As a by-product, we construct (asymptotically locally complex-hyperbolic) Kahler-Einstein metrics on the total spaces of the line bundles O(-m), m >= 3, over CP1.
