Query: Running coupling constants of the Luttinger liquid   Two running coupling constants of the Luttinger liquid are computed in the
fermion-fermion and fermion-antifermion channels. Nontrivial scaling laws are
found together with Landau poles. The apparent contradiction with the expected
vanishing of the beta functions is explained.
