Title: Kurke-LeBrun流形的普遍变形

Abstract: Twistor spaces are certain compact complex threefolds with an additional real fibre bundle structure. We focus here on twistor spaces over $3\mathbb{C}\mathbb{P}^2$. Such spaces are either small resolutions of double solids or they can be described as modifications of conic bundles. The last type is the more special one: they deform into double solids. We give an explicit description of this deformation, in a more general context. Show Chinese abstract

Abstract: 扭量空间是具有附加实纤维丛结构的某些紧致复三维流形。 我们在此关注的是关于 $3\mathbb{C}\mathbb{P}^2$的扭量空间。 这类空间或者是双重立体的小解，或者可以描述为圆锥束的修改。 后一种类型更为特殊：它们可以变形为双重立体。 我们在更一般的背景下给出了这种变形的显式描述。
