Query: Low temperature analysis of two dimensional Fermi systems with symmetric
  Fermi surface   We prove the convergence of the perturbative expansion, based on
Renormalization Group, of the two point Schwinger function of a system of
weakly interacting fermions in d=2, with symmetric Fermi surface and up to
exponentially small temperatures, close to the expected onset of
superconductivity
