Query: 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.
