Description
Summary:A bstract Motivated by the connection of string theory to cosmology or particle physics, we study solutions of type II supergravities having a four-dimensional de Sitter or Minkowski space-time, with intersecting D p -branes and orientifold O p -planes. Only few such solutions are known, and we aim at a better characterisation. Modulo a few restrictions, we prove that there exists no classical de Sitter solution for any combination of D 3 / O 3 and D 7 / O 7 , while we derive interesting constraints for intersecting D 5 / O 5 or D 6 / O 6 , or combinations of D 4 / O 4 and D 8 / O 8 . Concerning classical Minkowski solutions, we understand some typical features, and propose a solution ansatz. Overall, a central information appears to be the way intersecting D p / O p overlap each other, a point we focus on.
