最近，我们讨论了退化膜组态的新方面，它可以出现在杂化弦，微扰II型，或M/F理论的背景下。在这里，我们继续我们的研究退化膜配置，集中在两个应用。首先，我们展示了如何胶合的概念可以被视为一种工具，工程师的味道结构的F-理论和IIb型，如模型与散装物质和汤川纹理所产生的全纯零机制。我们发现，原则上有足够的结构来解决一些主要的味道问题，而不会产生外来的。特别是，我们展示了如何解决μ-问题，双重/三重态分裂和质子衰变。其次，我们描述了杂种单子结构的Fourier-Mukai变换，它出现在杂种线性σ模型真空的大体积极限中。退化结构又经常出现。人们可以用这一点来探索强耦合现象使用杂合/F-理论对偶。
A bstractRecently we discussed new aspects of degenerate brane configurations, which can appear in the context of heterotic strings, perturbative type II, or M/F-theory. Here we continue our study of degenerate brane configurations, focussing on two applications. First we show how the notion of gluing can be viewed as a tool to engineer flavour structures in F-theory and type IIb, such as models with bulk matter and with Yukawa textures arising from the holomorphic zero mechanism. We find that there is in principle enough structure to solve some of the major flavour problems without generating exotics. In particular, we show how this addresses the μ-problem, doublet/triplet splitting and proton decay. Secondly, we describe the Fourier-Mukai transform of heterotic monad constructions, which occur in the large volume limit of heterotic linear sigma model vacua. Degenerate structures again often appear. One may use this to explore strong coupling phenomena using heterotic/F-theory duality.
