Generalization of conformal Hamada operators

Abstract The six-derivative conformal scalar operator was originally found by Hamada in its critical dimension of spacetime, $$d=6$$ d = 6 . We generalize this construction to arbitrary dimensions d by adding new terms cubic in gravitational curvatures and by changing its coefficients of expansion i...
