An M-theory dS maximum from Casimir energies on Riemann-flat manifolds
Bruno Valeixo Bento, Miguel Montero
We initiate the study of flux compactifications on non-supersymmetric Riemann-flat manifolds (RFM's) with Casimir energy. While curvature and other corrections are suppressed in RF…

de Sitter no-go's for Riemann-flat manifolds and a link to semidefinite optimisation
Bruno Valeixo Bento, Miguel Montero
We establish a no-go theorem in the context of string and M-theory flux compactifications on Riemann-Flat manifolds with Casimir energy. Specifically, we show that no dS minimum ex…
