论文摘要
距离的猜想指出,在接近田间空间的无限距离时,无限的模式塔会呈指数光。我们认为,将距离猜想与最近的驯服猜想相结合时,可以解决此语句的固有路径依赖性。后者断言,有效理论是通过驯服的几何形状来描述的,并在耦合函数和野外空间上实现了强有力的约束。通过利用这些可驯服的约束,我们认为无限距离点附近的区域将分解为有限的许多部门,在这些部门中,可以建立与状态相关塔的路径独立陈述。然后,我们引入了更受限制的驯服功能,其中最多是多项式渐近生长,并认为它们足以描述已知的弦理论有效作用。值得注意的是,这些功能的多场依赖性可以通过边界附近每个扇区的一维线性测试路径重建。在四维有效理论中,这些测试路径被追溯为一组离散的宇宙弦溶液。这表明这种宇宙弦溶液可以用作研究任何四维有效野外理论的近似野外空间区域的强大工具。为了说明这些一般的观察,我们讨论了驯服和宇宙弦弦解决方案在IIB类弦理论的Calabi-yau压缩中的核心作用。
The Distance Conjecture states that an infinite tower of modes becomes exponentially light when approaching an infinite distance point in field space. We argue that the inherent path-dependence of this statement can be addressed when combining the Distance Conjecture with the recent Tameness Conjecture. The latter asserts that effective theories are described by tame geometry and implements strong finiteness constraints on coupling functions and field spaces. By exploiting these tameness constraints we argue that the region near the infinite distance point admits a decomposition into finitely many sectors in which path-independent statements for the associated towers of states can be established. We then introduce a more constrained class of tame functions with at most polynomial asymptotic growth and argue that they suffice to describe the known string theory effective actions. Remarkably, the multi-field dependence of such functions can be reconstructed by one-dimensional linear test paths in each sector near the boundary. In four-dimensional effective theories, these test paths are traced out as a discrete set of cosmic string solutions. This indicates that such cosmic string solutions can serve as powerful tool to study the near-boundary field space region of any four-dimensional effective field theory. To illustrate these general observations we discuss the central role of tameness and cosmic string solutions in Calabi-Yau compactifications of Type IIB string theory.
