  We consider sphere partition functions of TT deformed large N conformal field
theories in d=2,3,4,5 and 6 dimensions, computed using the flow equation. These
are shown to non-perturbatively match with bulk computations of $AdS_{d+1}$
with a finite radial cut-off. We then demonstrate how the flow equation can be
independently derived from a regularization procedure in defining TT operators
through a local Callan-Symanzik equation. Finally, we show that the sphere
partition functions, modulo bulk-counterterm contributions, can be reproduced
from Wheeler-DeWitt wave functions.
