One Hierarchy Spawns Another: Graph Deconstructions and the Complexity Classification of Conjunctive Queries

We study the problem of conjunctive query evaluation relative to a class of queries. This problem is formulated here as the relational homomorphism problem relative to a class of structures A, in which each instance must be a pair of structures such that the first structure is an element of A. We present a comprehensive complexity classification of... (more)

Definability of Cai-Fürer-Immerman Problems in Choiceless Polynomial Time

One of the most promising candidates for a logic capturing PTIME is Choiceless Polynomial Time (CPT). CPT can, in particular, define (the original version of) the Cai-Fürer-Immerman query, which separates fixed-point logic with counting from PTIME, and has remained the main benchmark for the expressibility of logics within PTIME. The CFI construction associates with each connected graph a set of CFI-graphs that can be partitioned into exactly two isomorphism classes called odd and even CFI-graphs. The problem is to decide, whether a given CFI-graph is odd or even. In the original version, the underlying graphs are linearly ordered, and for this case, Dawar, Richerby and Rossman proved that the CFI query is CPT-definable. However, the CFI query over general graphs remains one of the few known examples for which CPT-definability is open. We generalise the result by Dawar, Richerby and Rossman to the CFI query where the underlying graphs have colour classes of logarithmic size, and to graph classes with large maximal degree. For the latter, CPT-programs over sets of bounded rank suffice. Further, the use of "set-like objects" , instead of tuples, is unavoidable We introduce a notion of "sequence-like objects" based on the structure of their symmetry groups, and show that no CPT-program using only sequence-like objects can decide the CFI-query over graph classes with large maximal degree. From a more general perspective, this generalises a result by Blass, Gurevich, and van den Bussche about the power of isomorphism-invariant machine models (for PTIME) to a setting with counting.

Typed Nominal Rewriting

Nominal terms extend first-order terms with nominal features and as such constitute a meta-language for reasoning about the named variables of an object language in the presence of meta-level variables. This paper introduces a number of type systems for nominal terms of increasing sophistication and demonstrates their application in the area of equational reasoning. Two simple type systems inspired by Church's simply typed lambda calculus are presented where only well-typed terms are considered to exist, over which alpha-equivalence is then axiomatised. The first requires atoms to be strictly annotated whilst the second explores the consequences of a more relaxed de Bruijn style approach in the presence of atom-capturing substitution. A final type system of richer ML-style polymorphic types is then given in the style of Curry, where elements of the term language are deemed typeable or not only subsequent to the definition of alpha-equivalence. A type inference algorithm is described for this system and its application to equational reasoning explored, giving rise to two presentations of typed nominal rewriting and one of typed nominal algebra.

Completeness of Flat Coalgebraic Fixpoint Logics

Modal fixpoint logics traditionally play a central role in computer science, in particular in artificial intelligence and concurrency. The mu-calculus and its relatives are among the most expressive logics of this type. However, popular fixpoint logics tend to trade expressivity for simplicity and readability, and in fact often live within the single variable fragment of the mu-calculus. The family of such flat fixpoint logics includes, e.g., LTL, CTL, and the logic of common knowledge. Extending this notion to the generic semantic framework of coalgebraic logic enables covering a wide range of logics beyond the standard mu-calculus including, e.g., flat fragments of the graded mu-calculus and the alternating-time mu-calculus (such as alternating-time temporal logic ATL), as well as probabilistic and monotone fixpoint logics. We give a generic proof of completeness of the Kozen-Park axiomatization for such flat coalgebraic fixpoint logics.

Succinctness of Order-Invariant Logics on Depth-Bounded Structures

We study the expressive power and succinctness of order-invariant sentences of first-order (FO) and monadic second-order (MSO) logic on structures of bounded tree-depth. Order-invariance is undecidable in general and, thus, one strives for logics with a decidable syntax that have the same expressive power as order- invariant sentences. We show that on structures of bounded tree-depth, order-invariant FO has the same expressive power as FO. Our proof technique allows for a fine-grained analysis of the succinctness of this translation. We show that for every order-invariant FO sentence there exists an FO sentence whose size is elementary in the size of the original sentence, and whose number of quantifier alternations is linear in the tree-depth. We obtain similar results for MSO. It is known that the expressive power of MSO and FO coincide on structures of bounded tree-depth. We provide a translation from MSO to FO and we show that this translation is essentially optimal regarding the formula size. As a further result, we show that order-invariant MSO has the same expressive power as FO with modulo-counting quantifiers on bounded tree-depth structures.

Characterisation of Normalisation Properties for lambda-mu using Strict Negated Intersection Types

We show characterisation results for normalisation, head-normalisation, and strong normalisation for lambda-mu using intersection types. We reach these results for a strict notion of type assignment for lambda-mu that is the natural restriction of that of \cite{Bakel-Barbanera-Liguoro-TLCA'11} by limiting the type inclusion relation to just intersection elimination. We show that this system respects beta-mu-equality, by showing both soundness and completeness results. We then define a notion of reduction on derivations that corresponds to cut-elimination, and show that this is strongly normalisable. We use this strong normalisation result to show an approximation result, and through that a characterisation of head-normalisation. Using the approximation result, we show that there is a very strong relation between the system of \cite{Bakel-Barbanera-Liguoro-TLCA'11} and ours; we also show that our system extended with type variables essentially is that of \cite{Bakel-ITRS'10}. We also introduce a notion of type assignment that eliminates omega as an assignable type, and show, using the strong normalisation result for derivation reduction, that all terms typeable in this system are strongly normalisable as well, and show that all strongly normalisable terms are typeable.

Are Short Proofs Narrow? QBF Resolution is not so Simple

The groundbreaking paper 'Short proofs are narrow - resolution made simple' by Ben-Sasson and Wigderson (J. ACM 2001) introduces what is today arguably the main technique to obtain resolution lower bounds: to show a lower bound for the width of proofs. Another important measure for resolution is space, and in their fundamental work, Atserias and Dalmau (J. Comput. Syst. Sci. 2008) show that space lower bounds again can be obtained via width lower bounds. Here we assess whether similar techniques are effective for resolution calculi for quantified Boolean formulas (QBF). A mixed picture emerges. Our main results show that both the relations between size and width as well as between space and width drastically fail in Q-resolution, even in its weaker tree-like version. On the other hand, we obtain positive results for the expansion-based resolution systems EXP+Res and IR-calc, however only in the weak tree-like models. Technically, our negative results rely on showing width lower bounds together with simultaneous upper bounds for size and space. For our positive results we exhibit space and width-preserving simulations between QBF resolution calculi.

Complexity of Propositional Logics in Team Semantics

We classify the computational complexity of the satisfiability, validity and model-checking problems for propositional independence, inclusion, and team logic. Our main result shows that the satisfiability and validity problems for propositional team logic are complete for alternating exponential-time with polynomially many alternations.

Information Flow under Budget Constraints

Although first proposed in the database theory as properties of functional dependencies between attributes, Armstrong's axioms capture general principles of information flow by describing properties of dependencies between sets of pieces of information. This article generalizes Armstrong's axioms to a setting in which there is a cost associated with information. The proposed logical system captures general principles of dependencies between pieces of information constrained by a given budget.

Nested Weighted Automata

Recently there has been a significant effort to handle quantitative properties in formal verification and synthesis. While weighted automata over finite and infinite words provide a natural and flexible framework to express quantitative properties, perhaps surprisingly, some basic system properties such as average response time cannot be expressed using weighted automata, nor in any other know decidable formalism. In this work, we introduce nested weighted automata as a natural extension of weighted automata which makes it possible to express important quantitative properties such as average response time. In nested weighted automata, a master automaton spins off and collects results from weighted slave automata, each of which computes a quantity along a finite portion of an infinite word. Nested weighted automata can be viewed as the quantitative analogue of monitor automata, which are used in run-time verification. We establish an almost complete decidability picture for the basic decision problems about nested weighted automata, and illustrate their applicability in several domains. In particular, nested weighted automata can be used to decide average response time properties.

An effective characterization of the alternation hierarchy in two-variable logic

We give an algebraic characterization, based on the bilateral semidirect product of finite monoids, of the quantifier alternation hierarchy in two-variable first-order logic on finite words. As a consequence, we obtain a new proof that this hierarchy is strict. Moreover, by application of the theory of finite categories, we are able to make our characterization effective: that is, there is an algorithm for determining the exact quantifier alternation depth for a given language definable in two-variable logic.
