DESCRIPTION:We consider 2 limits in which the study of CFTs on curved 3-ma
 nifolds simplifies. In the limit of small deformations around the round 3-
 sphere\, we can use conformal perturbation theory to show that the round 3
 -sphere extremizes the free energy. In the large deformation limit of circ
 le bundles\, where the circle becomes small\, we can use thermal EFT to re
 late the free energy of different backgrounds\, as we illustrate with free
  and holographic CFTs.
