## Abstract We show that de Sitter vacua exist in simple extended supergravity theories. In the particular 𝒩 = 2 case we are considering here, we find a de Sitter solution of the supergravity theory with gravity and gravitini turned on by taking into account ψ^4^ torsion terms.

## Abstract We review the prospect of obtaining tree‐level de Sitter (dS) vacua and slow‐roll inflation models in string compactifications. Restricting ourselves to the closed string sector and assuming the absence of NSNS‐sources, we classify the minimal classical ingredients that evade the simple
