摘要
We analyzed the dimensional crossover from the Luttinger liquid to the Fermi liquid in continuous dimensions d between one and two by using Ward Identities for the density vertices. It is shown that the Fermi liquid is stable with respect to residual small q scattering by non singular interactions in any d > 1. Long range forces proportional to 1/\q\(alpha) modify these results for alpha greater than or equal to 2d - 2. Finally the relation between the above analysis and the method of bosonization in d = 2 is discussed.
