摘要翻译:
我们证明了任何具有$B_2=1$的VII类曲面都有曲线。这意味着在$b_2=1$情况下的“整体球壳猜想”:任何具有$b_2=1$的极小VII类曲面都允许一个整体球壳,因此它与已知列表中的一个曲面同构。证明的主要思想是证明在没有曲线的曲面$x$上的PU(2)-瞬子的模空间(如果存在这样的曲面)将包含一个闭黎曼曲面$y$,它的一般点对应于$x$上的不可过滤全纯丛。然后,我们从$x$parameterized的一族bundles传递到$y$parameterized的一族bundles,我们使用$y$的代数性来获得一个矛盾。证明基本上使用了Donaldson理论的技巧:PU(2)-瞬子模空间的紧性定理和曲面上的Kobayashi-Hitchin对应。

英文摘要:
We prove that any class $VII$ surface with $b_2=1$ has curves. This implies the "Global Spherical Shell conjecture" in the case $b_2=1$: Any minimal class $VII$ surface with $b_2=1$ admits a global spherical shell, hence it is isomorphic to one of the surfaces in the known list. The main idea of the proof is to show that a certain moduli space of PU(2)-instantons on a surface $X$ with no curves (if such a surface existed) would contain a closed Riemann surface $Y$ whose general points correspond to non-filtrable holomorphic bundles on $X$. Then we pass from a family of bundles on $X$ parameterized by $Y$ to a family of bundles on $Y$ parameterized by $X$, and we use the algebraicity of $Y$ to obtain a contradiction. The proof uses essentially techniques from Donaldson theory: compactness theorems for moduli spaces of PU(2)-instantons and the Kobayashi-Hitchin correspondence on surfaces.
