Ground State Entropy in Potts Antiferromagnets and Chromatic Polynomials
  We discuss recent results on ground state entropy in Potts antiferromagnets and connections with chromatic polynomials. These include rigorous lower and upper bounds, Monte Carlo measurements, large--$q$ series, exact solutions, and studies of analytic properties. Some related results on Fisher zeros of Potts models are also mentioned.
