Description
I will review recent developments concerning the possibility of a second-order chiral transition in the zero quark mass limit. Within the local potential approximation, using a phi^6 truncation, fixed points are found spanning the entire range of flavour numbers. I will discuss potential problems with this ansatz and review how the approach could be extended to global fixed-point potentials. I will also briefly comment on the N_c = 2 scenario.
