SUMMARY:The Tadpole Problem [Remote talk]
DESCRIPTION:I will discuss string theory compactifications where a large number of moduli is stabilized by fluxes. I will first present a conjecture which rules out the stabilization of all complex-structure moduli in F-theory at a generic point in moduli space by fluxes that satisfy the tadpole cancellation condition. Evidence for this conjecture comes from studying K3xK3 compactifications using evolutionary algorithms.  \nSubsequently\, I will discuss obstructions on flux compactifications coming from AdS/CFT holography. Here\, I will argue that it is not possible to obtain KKLT-like AdS vacua with very small cosmological constants by putting a bound on the central charge of the dual theory. These results have important consequences for the construction of de Sitter vacua in string theory.
