We study moduli stabilization for type IIB orientifold compactifications on Calabi‐Yau three‐folds with (non‐)geometric fluxes. For this setting it is possible to stabilize all closed‐string moduli classically without the need for non‐perturbative contributions, and examples of stable de‐Sitter constructions can be found in the literature which violate a prominent swampland conjecture. In this paper we derive general properties of non‐geometric flux‐compactifications, we argue that the contribution of fluxes to the tadpole cancellation conditions should be similar to D‐branes (and not anti‐D‐branes), and we exclude supersymmetric Minkowski vacua for certain cases. We also reassess known stable de‐Sitter constructions with (non‐)geometric H‐, F‐, Q‐ and R‐fluxes and argue that these are not consistent in string theory.

具有非几何通量的模量稳定— Ta贡献和De-Sitter真空的评论

我们研究具有（非）几何通量的Calabi-Yau三折形上IIB型向心形压实的模量稳定化。对于这种设置，可以经典地稳定所有闭弦模量而无需非扰动贡献，并且在文献中可以找到稳定的Deitter结构的示例，这些结构违反了著名的沼泽地猜想。在本文中，我们推导了非几何通量紧缩的一般性质，我们认为通量对the消除条件的贡献应类似于D谱（而不是反D谱），并且我们排除了超对称的Minkowski真空在某些情况下。我们还用（非）几何H-，F-，Q-和（非）几何重新评估已知的稳定de-Sitter结构R-磁通，并认为它们在弦论中是不一致的。
