Özet

We show that the scalar-tensor theory that arises in a rigorous D→3 limit of Lovelock gravity up to cubic order admits a holographic c-theorem and verify that the value of the c-function at the UV fixed point matches with the Weyl anomaly coefficient (up to an irrelevant factor). The constructed c-function is the same as one that follows from the "naive limit,"which is obtained by scaling the couplings by a factor of 1D-3, and then setting D=3.
