Local CFTs lie at the extrema of the sphere free energy tilde F for nonlocal CFT lines, and maximize it when unitary.
A reduced-dimension model places bosons in (d+1) dimensions and fermions in d dimensions to make perturbative RG analysis of NFL physics more tractable by taming logarithmic and higher divergences.
Long-range φ⁴ theories have RG beta functions that satisfy a gradient flow with A matching the sphere free energy F̃ at leading nontrivial order.
Large-N saddle-point calculation confirms the Lukyanov-Zamolodchikov conjecture for boundary free energy in the spherical brane model to O(1/N) and connects it to the RG running of the coupling g.
