The Fermi arc is a striking manifestation of the strong-correlation physics in high-TcTc cuprates. In this paper, implications of the metallic transport in the lightly hole-doped regime of the cuprates, where the Fermi arcs are found, are examined in conjunction with competing interpretations of the Fermi arcs in terms of small hole pockets or a large underlying Fermi surface. It is discussed that the latter picture provides a more natural understanding of the metallic transport in view of the Mott-limit argument. Furthermore, it is shown that a suitable modeling of the Fermi arcs in the framework of the Boltzmann theory allows us to intuitively understand why the transport properties are apparently determined by a “small” carrier density even when the underlying Fermi surface, and hence kFkF, is large.
