Luttinger Theorem in One Dimensional Metals
  One dimensional metals are described by Luttinger liquid theory. Recent experiments have addressed the relation between this non-Fermi liquid behavior and the existence of a Fermi surface. We show that Luttinger's theorem, with few modifications, holds for the one-dimensional Tomonaga-Luttinger model. The implications for the high temperature superconductors are discussed.
