Is there a novel Einstein–Gauss–Bonnet theory in four dimensions?
Abstract No! We show that the field equations of Einstein–Gauss–Bonnet theory defined in generic $$D>4$$ D>4 dimensions split into two parts one of which always remains higher dimensional, and hence the theory does not have a non-trivial limit to $$D=4$$ D=4 . Therefore, the recently introduce...
