Abstract
A relation between the spectrum and correlation exponents of the Luttinger model is argued to be a general property of a universality class called "Luttinger liquids." The spinless fermion model equivalent to the Heisenberg-Ising - chain in a field is argued to belong to this class, allowing for the first time the systematic calculation of its correlation exponents.
