研究具有SU(5)奇点的奇异Calabi-Yau四重上的f -理论紧化和m -理论紧化。在m理论方面,这实现了与物质的三维= 2超对称量规理论,并且四倍的紧化解对应于传递到量规理论的库仑分支。这些理论的经典相结构有一个简单的表征,即规范群的基本Weyl室的亚楔。这种相位结构在小分辨率的Calabi-Yau四倍网络中也有对应。我们确定了每个相位的几何实现,这在很大程度上取决于协维2和3的光纤结构,包括网络结构,这是通过翻翻转换来实现的。这导致了一组小分辨率,它们没有标准的代数或环实现,而是通过沿余维2(物质)轨迹的flops获得的。
We consider F-theory and M-theory compactifications on singular Calabi-Yau fourfolds with an SU (5) singularity. On the M-theory side this realizes three-dimensional= 2supersymmetricgaugetheorieswithmatter, andcompactificationonaresolutionof the fourfold corresponds to passing to the Coulomb branch of the gauge theory. The classical phase structure of these theories has a simple characterization in terms of subwedges of the fundamental Weyl chamber of the gauge group. This phase structure has a counterpart in the network of small resolutions of the Calabi-Yau fourfold. We determine the geometric realization of each phase, which crucially depends on the fiber structure in codimension 2 and 3, including the network structure, which is realized in terms of flop transitions. This results in a set of small resolutions, which do not have a standard algebraic or toric realization, but are obtained by flops along codimension 2 (matter) loci.
