Abstract
Abstract
A simple, KKLT-like construction of de Sitter vacua in type IIA string theory is presented in an STU model with guidance from string theory U-duality and with an up- lifting anti-D6-brane. In four dimensions the model is reduced to
$$ \mathcal{N} $$
N
= 1 supergravity with three chiral multiplets, namely S, T and U , as well as one nilpotent multiplet representing the anti-D6-brane. We briefly discuss also a generalization with seven moduli.
