d3 and d5 maximally SUSY gauged supergravities are considered in the parame
terization (flow) of the full scalar coset, where the kinetic term for scal
ars takes the standard field theory form and the bulk potential is an arbit
rary one subject to consistent parameterization. From such SG duals, we cal
culate d2 and d4 holographic conformal anomalies which depend on the bulk s
calar potential. AdS/CFT correspondence suggests that such an SG-side confo
rmal anomaly should be identified with a (non-perturbative) QFT conformal a
nomaly (taking account of radiative corrections) for the theory on the boun
dary of the AdS space. In the limit of a constant bulk potential and a sing
le scalar, the d4 result reproduces the known exact conformal anomaly corre
sponding to maximally SUSY super Yang-Mills theory coupled to N = 4 conform
al supergravity.
