On the Expression Complexity of Equivalence and Isomorphism of Primitive Positive Formulas

Abstract

We study the complexity of
equivalence and isomorphism on
primitive positive formulas with respect to a given structure.
We study these problems for various fixed structures;
we present generic hardness and complexity class containment
results, and give classification theorems for the case of
two-element (boolean) structures.
