Mirror symmetry concerns pairs of Calabi–Yau compactifications related by exchanging the geometric data of the two theories. In the flux setting, one considers compactifications of…
Let be a Calabi–Yau manifold, and let be its canonical mirror dual in the absence of fluxes. Consider type IIB (A) string theory compactified on…
Let be an internal manifold with isometries, let be its generalized Kac–Moody current algebra, and let flux backgrounds define the reduced…
Flux mirror-symmetry conjecture. For every flux background , there exists a mirror background whose moduli satisfy these correspondences. A…
Consider a flux background in which a number of moduli are fixed, and let the background satisfy a tadpole constraint. Quantitative tadpole conjecture. The tadpole should grow appr…
Let a Calabi–Yau compactification have a large number of complex-structure moduli, and let background fluxes be subject to the tadpole bound. Tadpole conjecture. It should be impos…
Consider fluxes that stabilize moduli in a flux compactification, and let the tadpole charge be the charge induced by those fluxes. Tadpole conjecture. The tadpole charge induced b…
Flux-dependent identification conjecture. For each flux configuration , an identification like exists.
Consider a flux background whose defining three-form receives higher-derivative corrections. Let the corrected defining three-form be the three-form specifying the corrected geomet…
Scale-separation conjecture. Classical de Sitter solutions cannot have at the same time a large internal volume, a small string coupling, a bounded number of orientifolds and quant…
Intersecting-source instability conjecture. Classical de Sitter solutions with intersecting sources are unstable.
Parallel-source conjecture. There is no classical de Sitter solution with parallel sources.
Nonassociative phase-space algebra conjecture. After three T-dualities, the coordinates satisfy a nonassociative phase-space coordinate algebra whose Jacobiator reproduces this 3-b…
In a closed-string background with three-form flux, let , , and denote space-time coordinates, and let be their three-bracket. Three-bracket conject…
Let the compact geometry have sixteen nodes locally modeled on conifolds, with RR-flux through an -cycle and RR-flux through the -cycle. Consider fluxes who…
