Weyl–invariant scalar–tensor gravities from purely metric theories
Abstract We describe a method to generate scalar–tensor theories with Weyl symmetry, starting from arbitrary purely metric higher derivative gravity theories. The method consists in the definition of a conformally-invariant metric $$\hat{g}_{\mu \nu }$$ g ^ μ ν , that is a rank (0,2)-tensor construc...
