The U(n)v×U(n)A four-Fermi model in 2+1 dimensions is renormalizable and exhibits dynamical symmetry breaking. We prove Goldstone's theorem to all orders in 1/Nf expansion. We calculate the low energy interactions of fermions and Goldstone bosons, and explicity verify the Goldberger-Trieman relation.
