Abstract
We study compactifications of type IIA supergravity on cosets exhibiting SU ( 3 ) structure. We establish the consistency of the truncation based on left-invariance, providing a justification for the choice of expansion forms which yields gauged N = 2 supergravity in four dimensions. We explore N = 1 solutions of these theories, emphasizing the requirements of flux quantization, as well as their non-supersymmetric companions. In particular, we obtain a no-go result for de Sitter solutions at string tree level, and, exploiting the enhanced leverage of the N = 2 setup, provide a preliminary analysis of the existence of de Sitter vacua at all string loop order.
