摘要翻译:
对于所有最小VII类曲面$S$和所有可能的Gauduchon度量$G$,我们显式地描述了在$C_1(E)=C_1(K)$和$C_2(E)=0$的秩2向量丛$E$上具有$\det E\cong K$的多稳定全纯结构$E$的模空间$M^{pst}_g(S,E)$。这些曲面$S$是非椭圆和非Kaehler复曲面,最近被完全分类。当$S$为半曲面或抛物型井上曲面时,$M^{pst}_g(S,E)$总是紧致的一维复圆盘。当$S$是一个Enoki曲面时,我们得到了一个具有有限个横向自交点的复圆盘,当$G$在Gauduchon度量空间中变化时,该自交点的数目变得任意大。$m^{pst}_g(S,E)$可以用PU(2)-瞬子的模空间来识别。上述类型的单丛的模空间导致了有趣的非Hausdorff奇异一维复空间的例子。

英文摘要:
We describe explicitly the moduli spaces $M^{pst}_g(S,E)$ of polystable holomorphic structures $E$ with $\det E\cong K$ on a rank 2 vector bundle $E$ with $c_1(E)=c_1(K)$ and $c_2(E)=0$ for all minimal class VII surfaces $S$ with $b_2(S)=1$ and with respect to all possible Gauduchon metrics $g$. These surfaces $S$ are non-elliptic and non-Kaehler complex surfaces and have recently been completely classified. When $S$ is a half or parabolic Inoue surface, $M^{pst}_g(S,E)$ is always a compact one-dimensional complex disc. When $S$ is an Enoki surface, one obtains a complex disc with finitely many transverse self-intersections whose number becomes arbitrarily large when $g$ varies in the space of Gauduchon metrics. $M^{pst}_g(S,E)$ can be identified with a moduli space of PU(2)-instantons. The moduli spaces of simple bundles of the above type leads to interesting examples of non-Hausdorff singular one-dimensional complex spaces.
