A bstract The ?? -complete cosmology developed by Hohm and Zwiebach classifies the O( d, d ; ?) invariant theories involving metric, b -field dilaton that only depend on time, to all orders in . Some of these feature non-perturbative isotropic de Sitter vacua string frame, generated infinite number higher-derivatives multiplets. Extending ansatz, we construct stable unstable solutions Einstein ...

Abstract The anticanonical complex generalizes the Fano polytope from toric geometry and has been used to study varieties with torus action so far. We provide an explicit description of for complete intersections in defined by non-degenerate systems Laurent polynomials. As application, we classify terminal threefolds that are embedded into a fake weighted projective space via general system
