Abstract

Extending a prior result of Contucci et al (Comm. Math. Phys. 2013), we determine the free energy of the Potts antiferromagnet on the Erd\"os-R\'enyi random graph at all temperatures for average degrees d(2k1)lnk2k1/2d \le (2k-1)\ln k - 2 - k^{-1/2}. In particular, we show that for this regime of dd there does not occur a phase transition.
