AN APPLICATION OF FIRST-ORDER LOGIC TO THE STUDY OF RECOGNIZABLE LANGUAGES
2004
International journal of algebra and computation
A variation of first-order logic with variables for exponents is developed to solve some problems in the setting of recognizable languages on the free monoid, accommodating operators such as product, bounded ...
Restricting the operators to powers and product, analogous results are obtained for recognizable languages of an arbitrary finitely generated monoid M . ...

Monadic Second-Order Logic for Graphs: Algorithmic and Language Theoretical Applications
[chapter]
2009
Lecture Notes in Computer Science
This tutorial will present an overview of the use of Monadic Second-Order Logic to describe sets of finite graphs and graph transformations, in relation with the notions of tree-width and clique-width. ...
It will review applications to the construction of algorithms, to Graph Theory and to the extension to graphs of Formal Language Theory concepts. ...
We first explain the role of Logic. ...

MK-fuzzy Automata and MSO Logics
2017
Electronic Proceedings in Theoretical Computer Science
We introduce an MK-fuzzy MSO logic and show the expressive equivalence of a fragment of this logic with MK-fuzzy automata, i.e., a B\"uchi type theorem. ...
We introduce MK-fuzzy automata over a bimonoid K which is related to the fuzzification of the McCarthy-Kleene logic. ...
We show that the strong support, related to the first component of the elements in K, of a deterministically recognizable MK-fuzzy language is a recognizable language. ...

Recognizable Sets of Graphs, Hypergraphs and Relational Structures: A Survey
[chapter]
2004
Lecture Notes in Computer Science
The general framework of this research which associates tightly algebraic notions (equational and recognizable sets) and Monadic Second-Order logic (for defining sets and transformations of graphs, hypergraphs ...
New results on the recognizability of sets of finite graphs, hypergraphs and relational structures are presented. ...
Hence Monadic Second-Order logic (MS logic in short) is an appropriate language for specifying sets of graphs. It can be seen as an alternative to the non-existing notion of graph automaton. ...

Algebraic recognizability of languages
[article]
2006
arXiv
pre-print
Recognizable languages of finite words are part of every computer science cursus, and they are routinely described as a cornerstone for applications and for theory. ...
We would like to briefly explore why that is, and how this word-related notion extends to more complex models, such as those developed for modeling distributed or timed behaviors. ...
Recognizability Based on the examples of words and trees, the natural language for logical definability of recognizable sets would seem to be MSO, monadic second order logic. ...

Monadic Second-Order Logic over Rectangular Pictures and Recognizability by Tiling Systems

Information and Computation
The proof is based on the Ehrenfeucht Fra@ sse technique for first-order logic and an implementation of"threshold counting" within tiling systems. ] ...
It is shown that a set of pictures (rectangular arrays of symbols) is recognized by a finite tiling system iff it is definable in existential monadic second-order logic. ...

Logical definability on infinite traces
1996
Theoretical Computer Science
The main results of the present paper are the equivalence of definability by monadic secondorder logic and recognizability for real trace languages, and that first-order definable, star-free, and aperiodic ...
This generalizes results on infinite words and on finite traces to infinite traces. It closes an important gap in the different characterizations of recognizable languages of infinite traces. ...
We also thank the anonymous referees from ICALP and especially from Theoretical Computer Science for the valuable comments which helped improving the presentation of this paper. ...

Recognizability in the Simply Typed Lambda-Calculus
[chapter]
2009
Lecture Notes in Computer Science
Using intersection types, we generalize the notions of automata for strings and trees so as to grasp recognizability for λ-terms. ...
We then expose the closure properties of this notion and present some of its applications. ...
As we wish to use this notion of recognizability so as to describe particular sets of λ-terms, it would be nice to obtain a connection with some logic. First-order logic would be a first step. ...
