Kosterlitz-Thouless Transition Line for the Two Dimensional Coulomb Gas
  With a rigorous renormalization group approach, we study the pressure of the two dimensional Coulomb Gas along a small piece of the Kosterlitz-Thouless transition line, i.e. the boundary of the dipole region in the activity-temperature phase-space.
