Strictly Piecewise (SP) languages are a subclass of regular languages which encode certain kinds of long-distance dependencies that are found in natural languages. Like the classe...
Quotients and factors are important notions in the design of various computational procedures for regular languages and for the analysis of their logical properties. We propose a n...
The study of finite automata and regular languages is a privileged meeting point of algebra and logic. Since the work of Büchi, regular languages have been classified according ...
Angluin showed that the class of regular languages could be learned from a Minimally Adequate Teacher (mat) providing membership and equivalence queries. Clark and Eyraud (2007) sh...
Abstract. It is well known that modelchecking and satisfiability of Linear Temporal Logic (LTL) are Pspace-complete. Wolper showed that with grammar operators, this result can be e...
We explore the natural question of whether all NP-complete problems have a common restriction under which they are polynomially solvable. More precisely, we study what languages a...
Abstract. Blocker and coblocker sets are regular languages involved in the algorithmic solution of the Regular Post Embedding Problem. We investigate the computability of these lan...
We define a language to be overlap-free if any two distinct strings in the language do not overlap with each other. We observe that overlap-free languages are a proper subfamily of...
We propose a new approach to the notion of recognition, which departs from the classical definitions by three specific features. First, it does not rely on automata. Secondly, it...
