A bstract We elaborate on recent results regarding the self-consistency of de Sitter vacua in LARGE-volume scenario type IIB string theory. In particular, we analyze to what extent control over warping, curvature and g s corrections depends topology orientifold/brane data a compactification. compute general bound magnitude these which strongly constrains D3 tadpole. The minimally required tadpo...

A bstract Type IIB flux vacua based on Landau-Ginzburg models without Kähler deformations provide fully-controlled insights into the non-geometric and strongly-coupled string landscape. We show here that supersymmetric configurations at Fermat point of 1 9 model, which were found long-time ago to saturate orientifold tadpole, leave a number massless fields, however are not all flat directions s...
