    “…These constraints can rule out supergravity theories which &nbsp;otherwise look perfectly healthy as effective field theories of quantum gravity. We also test the proposed constraints by comparing them with explicit string models,&nbsp;in particular with F-theory compactifications to four dimensions.…”
