Construction of a 2d Fermi Liquid

The temperature zero renormalized perturbation expansions of a class
of interacting manyfermion models in two space dimensions with
"asymmetric" Fermi surfaces have nonzero radius of convergence. One
consequence of the convergence is the existence of a discontinuity in
the particle number density at the Fermi surface. In this talk, I
intend to introduce the models, sketch the main results and then
introduce the renormalization group map, which provides both the
intuition and the framework for the proof.
