论文摘要
我们在四个维度上研究了杂种/II型双对的模量空间,n = 2个超对称性,对应于II型II型方面的非几何calabi-yau背景,并在异质方面进行T折压缩。矢量多重模量模量空间仅在杂种描述中接受扰动校正,并且在两个描述中都非扰动校正。我们使用其奇异性结构和异扰性双重性组明确地将扰动校正推向了异构的四维优势。我们还得出了精确的超级模型空间,该空间既不会在字符串耦合中也不会在$α'$中接收校正。
We study the moduli spaces of heterotic/type II dual pairs in four dimensions with N=2 supersymmetry corresponding to non-geometric Calabi-Yau backgrounds on the type II side and to T-fold compactifications on the heterotic side. The vector multiplets moduli space receives perturbative corrections in the heterotic description only, and non-perturbative correction in both descriptions. We derive explicitely the perturbative corrections to the heterotic four-dimensional prepotential, using the knowledge of its singularity structure and of the heterotic perturbative duality group. We also derive the exact hypermultiplets moduli space, that receives corrections neither in the string coupling nor in $α'$.
