Summary
We define the Maldacena–Núñez no-go theorem for supergravity compactifications and show that it implies that there are no de Sitter or Minkowski compactifications, both in massless and in massive supergravity. The case of no Randall–Sundrum solutions in d = 5 gauged supergravity is treated separately. The swampland conjecture for string theory compactifications is based on some “sporadic” results, and there is a more general no-go theorem, but there are loopholes.
