On the Decidability and Complexity of the Theory of Presburger Arithmetic

Koduri Siddharth Choudary


We consider the first order theory over Natural numbers with addition and order relations known as Presburger Arithmetic. We discuss a known decision procedure called Quantifier Elimination and its complexity. Further, we look at specific subclasses of this theory by imposing conditions on the Quantifier prefixes (such as fixing the number of alternations between universal and existential quantifiers or fixing the maximum length of a quantifier block without alternations, etc.) to give a more precise complexity bounds for these subclasses. Finally as an application, we consider the reachability problem in some classes of reversal bounded systems and give a reduction to Presburger Arithmetic.
