On Presburger arithmetic extended with non-unary counting quantifiers

چکیده
We consider a first-order logic for the integers with addition. This extends classical by modulo-counting, threshold-counting and exact-counting quantifiers, all applied to tuples of variables (here, residues are given as terms while moduli thresholds explicitly). Our main result shows that satisfaction this is decidable in two-fold exponential space. If only threshold- quantifiers allowed, we prove an upper bound alternating time linearly many alternations. latter almost matches Berman's exact complexity without counting quantifiers. To obtain these results, first translate into polynomial (which already proves second result). handle remaining modulo-counting tuples, reduce them doubly single elements. For provide quantifier elimination procedure similar Reddy Loveland's analyse growth coefficients, constants, appearing process. The bounds obtained way allow restrict quantification original formula bounded size which then implies mentioned above. incomparable considered Chistikov et al. 2022. They more general operations but unary move from non-unary non-trivial, since, e.g., version H\"artig results undecidable theory.

On Presburger Arithmetic Extended with Modulo Counting Quantifiers
We consider Presburger arithmetic (PA) extended with modulo counting quantifiers. We show that its complexity is essentially the same as that of PA, i.e., we give a doubly exponential space bound. This is done by giving and analysing a quantifier elimination procedure similar to Reddy and Loveland’s procedure for PA. We also show that the complexity of the automata-based decision procedure for ...
متن کاملPresburger Arithmetic with Unary Predicates Is 1 1 Complete
We give a simple proof characterizing the complexity of Pres-burger arithmetic augmented with additional predicates. We show that Pres-burger arithmetic with additional predicates is 1 1 complete. Adding one unary predicate is enough to get 1 1 hardness, while adding more predicates (of any arity) does not make the complexity any worse.
متن کاملOn Winning Strategies with Unary Quantifiers
A combinatorial argument for two nite structures to agree on all sentences with bounded quantiier rank in rst-order logic with any set of unary generalized quantiiers, is given. It is known that connectivity of nite structures is neither in monadic 1 1 nor in L !! (Q u), where Q u is the set of all unary generalized quantiiers. Using this combinatorial argument and a combination of second-order...
متن کاملParametric Presburger Arithmetic: Complexity of Counting and Quantifier Elimination
We consider an expansion of Presburger arithmetic which allows multiplication by k parameters t1, . . . , tk. A formula in this language defines a parametric set St ⊆ Z d as t varies in Z, and we examine the counting function |St| as a function of t. For a single parameter, it is known that |St| can be expressed as an eventual quasi-polynomial (there is a period m such that, for sufficiently la...
متن کاملThe Universal Fragment of Presburger Arithmetic with Unary Uninterpreted Predicates is Undecidable
The first-order theory of addition over the natural numbers, known as Presburger arithmetic, is decidable in double exponential time. Adding an uninterpreted unary predicate to the language leads to an undecidable theory. We sharpen the known boundary between decidable and undecidable in that we show that the purely universal fragment of the extended theory is already undecidable. Our proof is ...
