We study the expression complexity of two basic problems involving the comparison of primitive positive formulas: equivalence and containment. We give two generic hardness results for the studied problems, and discuss evidence that they are optimal and yield, for each of the problems, a complexity trichotomy. © 2011 Springer-Verlag.
