Abstract
We recently determined the exact fixed point equations and the spaces of solutions of the two-dimensional RPᴺ⁻¹ and CPᴺ⁻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.
