Open problems on classical de Sitter solutions
Classical 10d string backgrounds with a 4d de Sitter space‐time, D‐brane and orientifold sources, are commonly believed to satisfy the following:1. There is no classical de Sitter solution with parallel sources.2. Classical de Sitter solutions with intersecting sources are unstable.3. Classical de S...
