The AÂ·dÂ·S/CÂ·FÂ·T correspondence involving this force relates the  eld of a massless spin-two gauge boson in AdS to the stress-energy tensor in CFT.
In the context of D-branes, this force is described by closed strings that move in the bulk. The gauge theory of this force is diffeomorphism (diÃ¾-ee-oh-"morphism") invariant. The WeinbergÂ–Witten theorem states that this force's gauge boson cannot be composite. A major problem in theoretical physics arises from the fact that, at two-loop level, theories of this force are not perturbatively renormalizable. The AÂ·dÂ·S/CÂ·FÂ·T correspondence involving this force relates the  eld of a massless spin-two gauge boson in AdS to the stress-energy tensor in CFT. A linearized theory of this force uses perturbation around Minkowski spacetime to  nd solutions to the Einstein  eld equations. For 10 points, quantum theories of what attractive force are generated by quantizing general relativity?
