摘要
对于维数≥3的紧化K¨ahler流形M中具有支撑点B的有效因子A,下列是反律的。a) M \ B具有一个C∞多次调和耗尽函数,其Levi形式在M \ B的紧子集外点方向上至少有3个正特征值。b) [A] | A的正规束b是拓扑平凡的。
A remark on pseudoconvex domains with analytic complements in compact Kähler manifolds
For an effective divisor A with support B in a compact K¨ahler manifold M of dimension ≥ 3, the following are antinomic. a) M \ B has a C ∞ plurisubharmonic exhaustion function whose Levi form has pointwise at least 3 positive eigenvalues outside a compact subset of M \ B . b) [ A ] | B , the normal bundle of A , is topologically trivial.
