Abstract
We consider a renormalization group study of the problem of coupled st ripes of holes in cuprates. We use a model of a mesh of horizontal and vertical stripes and study the problem of superconductivity via the J osephson coupling. We discuss the evolution of the Fermi surface with doping and temperature, the existence of Luttinger and/or Fermi liquid behavior, the presence of preformed Cooper pairs, and the symmetry an d magnitude of the superconducting order parameter.
