研究了有限交换群Λ的三维轨道奇点C3/Λ的D-膜分解的拓扑性质。D膜真空模空间填充了时空背景，Fayet-Iliopoulos参数控制了爆破的大小。这个D膜真空模量空间可以经典地描述一个规范的线性西格玛模型，它被证明是非通用的方式，投影出非几何区域在其相图中，从许多角度来看，预期。
We study topological properties of the D-brane resolution of three-dimensional orbifold singularities, C3/Λ , for finite abelian groups Λ. The D-brane vacuum moduli space is shown to fill out the backgroun space-time with Fayet-Iliopoulos parameters controlling the size of the blow-ups. This D-brane vacuum moduli space can be classically described by a gauged linear sigma model, which is shown to be non-generic in a manner that projects out non-geometric regions in its phase diagram, as anticipated from a number of perspectives.
