  The Holographic Wess--Zumino (HWZ) consistency conditions are shown through a
step by step mapping of renormalization group flows to Hamiltonian systems, to
lead to the Holographic anomaly. These conditions codify how the energy scale,
when treated as the emergent bulk direction in Holographic theories, is put on
equal footing as the other directions of the space the field theory inhabits.
So, this is a defining feature of theories possessing local Holographic bulk
duals. In four dimensional Holographic conformal field theories, the $a$ and
$c$ anomaly coefficients are equated, and this is seen as a defining property
of theories which possess General Relativity coupled to matter as a dual.
Hence, showing how the former consistency conditions leads to the latter
relation between anomaly coefficients adds evidence to the claim that the HWZ
conditions are a defining feature of theories possessing local gravity duals.
