There has been much activity in recent months regarding upper bounds on the density of sets containing no 3-term arithmetic progressions. We shall give an overview of some of these developments and subsequently examine the corresponding lower bounds for this problem, which are partly probabilistic in nature. This includes joint work with Ben Green.
