Oh, wait, O8 de Sitter may be unstable!
Iosif Bena, G. Bruno De Luca, Mariana Graña +1
We analyze the stability of four-dimensional de Sitter vacua constructed by compactifying massive Type IIA supergravity in the presence of two O8 sources [1]. When embedded in Stri…
New de Sitter Solutions in Ten Dimensions and Orientifold Singularities
Clay Cordova, G. Bruno De Luca, Alessandro Tomasiello
In previous work, we found ten-dimensional solutions to the supergravity equations of motion with a dS factor and O8-planes. We generalize this analysis and obtain other soluti…
Classical de Sitter Solutions of Ten-Dimensional Supergravity
Clay Cordova, G. Bruno De Luca, Alessandro Tomasiello
We find four-dimensional de Sitter compactifications of type IIA supergravity by directly solving the ten-dimensional equations of motion. In the simplest examples, the internal sp…
