摘要
假设 \(H^k(D,\mathscr {O}) = 0\) for\(2 \le k \le n - 1\) 并且存在一个正维度的复数李群 G，使得 D 上所有微分琐碎的全形主 G 束都是全形琐碎的。那么，我们证明 D 是 Stein。
Unramified Riemann Domains Satisfying the Oka–Grauert Principle over a Stein Manifold
Let \((D, \pi )\) be an unramified Riemann domain over a Stein manifold of dimension n. Assume that \(H^k(D,\mathscr {O}) = 0\) for \(2 \le k \le n - 1\) and there exists a complex Lie group G of positive dimension such that all differentiably trivial holomorphic principal G-bundles on D are holomorphically trivial. Then, we prove that D is Stein.
