An important open question in complexity theory is whether the circuit complexity class TC0 is (strictly) weaker than LOGSPACE. This paper considers this question from the viewpoint of descriptive complexity theory. TC0 can be characterized as the class of queries expressible by the logic FOC(<,+,×), which is first-order logic augmented by counting quantifiers on ordered structures that have ad...

First-order (FO) logic and its extensions play an important role in many branches of (theoretical) computer science. Examples that will be considered in this paper are automata theory and descriptive complexity. Since Büchi’s and Elgot’s famous characterization of the regular string languages as the sets of models of (existential) monadic second-order (MSO) sentences, (existential) MSO logic ha...

Polyadic Higher-Order Fixpoint Logic (PHFL) is a modal fixpoint logic obtained as the merger of Higher-Order Fixpoint Logic (HFL) and the Polyadic μ-Calculus. Polyadicity enables formulas to make assertions about tuples of states rather than states only. Like HFL, PHFL has the ability to formalise properties using higher-order functions. We consider PHFL in the setting of descriptive complexity...

The computational complexity of a problem is the amount of resources, such as time or space, required by a machine that solves the problem. The descriptive complexity of problems is the complexity of describing problems in some logical formalism over finite structures. One of the exciting developments in complexity theory is the discovery of a very intimate connection between computational and ...
