On the $R{P}^{N-1}$ and $C{P}^{N-1}$ universality classes

Abstract

We recently determined the exact fixed point equations and the spaces of solutions of the two-dimensional $R{P}^{N-1}$ and $C{P}^{N-1}$ models using scale invariant scattering theory. Here we discuss subtleties hidden in some solutions and related to the difference between ferromagnetic and antiferromagnetic interaction.
