本文研究了N = 1杂化弦真空中对应于余维3中点状丛奇点的新的非微扰现象。这些简并导致了新的四维红外物理，其特征在于光孤子态，其起源在双F理论模型中得到解释。我们还证明了这种现象普遍存在于E7→E6的Higgsing中，并详细描述了相应的束跃迁。
We study new nonperturbative phenomena in N = 1 heterotic string vacua corresponding to pointlike bundle singularities in codimension three. These degenerations result in new four-dimensional infrared physics characterized by light solitonic states whose origin is explained in the dual F-theory model. We also show that such phenomena appear generically in E7→E6 higgsing and describe in detail the corresponding bundle transition.
