Regular Cost Functions, Part I: Logic and Algebra over Words [PDF]

open access: yesLogical Methods in Computer Science, 2013
The theory of regular cost functions is a quantitative extension to the classical notion of regularity. A cost function associates to each input a non-negative integer value (or infinity), as opposed to languages which only associate to each input the ...

Logic Meets Algebra: the Case of Regular Languages [PDF]

open access: yesLogical Methods in Computer Science, 2007
The study of finite automata and regular languages is a privileged meeting point of algebra and logic. Since the work of Buchi, regular languages have been classified according to their descriptive complexity, i.e.

Regular tree languages, cardinality predicates, and addition-invariant FO [PDF]

open access: yes, 2011
This paper considers the logic FOcard, i.e., first-order logic with cardinality predicates that can specify the size of a structure modulo some number.

An Introduction to Predictive Processing Models of Perception and Decision‐Making

open access: yesTopics in Cognitive Science, EarlyView., 2023
Abstract The predictive processing framework includes a broad set of ideas, which might be articulated and developed in a variety of ways, concerning how the brain may leverage predictive models when implementing perception, cognition, decision‐making, and motor control.

Weighted Logics for Nested Words and Algebraic Formal Power Series [PDF]

open access: yes, 2010
Nested words, a model for recursive programs proposed by Alur and Madhusudan, have recently gained much interest. In this paper we introduce quantitative extensions and study nested word series which assign to nested words elements of a semiring. We show

Modal Ω-Logic: Automata, Neo-Logicism, and Set-Theoretic Realism [PDF]

open access: yes, 2019
This essay examines the philosophical significance of $\Omega$-logic in Zermelo-Fraenkel set theory with choice (ZFC). The duality between coalgebra and algebra permits Boolean-valued algebraic models of ZFC to be interpreted as coalgebras.

On Intuitionistic Fuzzy Context-Free Languages

open access: yesJournal of Applied Mathematics, 2013
Taking intuitionistic fuzzy sets as the structures of truth values, we propose the notions of intuitionistic fuzzy context-free grammars (IFCFGs, for short) and pushdown automata with final states (IFPDAs).

On Varieties of Automata Enriched with an Algebraic Structure (Extended Abstract)

open access: yes, 2014
Eilenberg correspondence, based on the concept of syntactic monoids, relates varieties of regular languages with pseudovarieties of finite monoids.

Quantum finite automata and linear context-free languages: a decidable problem [PDF]

open access: yes, 2013
We consider the so-called measure once finite quantum automata model introduced by Moore and Crutchfield in 2000. We show that given a language recognized by such a device and a linear context-free language, it is recursively decidable whether or not ...

A Fibrational Approach to Automata Theory [PDF]

open access: yes, 2015
For predual categories C and D we establish isomorphisms between opfibrations representing local varieties of languages in C, local pseudovarieties of D-monoids, and finitely generated profinite D-monoids.
