Hyperbolic tilings and formal language theory [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2013
In this paper, we try to give the appropriate class of languages to which belong various objects associated with tessellations in the hyperbolic plane.

Formal Semantics of the CHART Transformation Language [PDF]

open access: yes, 2011
The relational data model is based on sets of tuples, i.e. it does not allow duplicate tuples an a relation. Many database languages and systems do require multi-set semantics though, either because of functional requirements or because of the high costs

A Theory of Formal Choreographic Languages

open access: yesLogical Methods in Computer Science, 2023
We introduce a meta-model based on formal languages, dubbed formal choreographic languages, to study message-passing systems. Our framework allows us to generalise standard constructions from the literature and to compare them. In particular, we consider notions such as global view, local view, and projections from the former to the latter.

Formal Languages, Formally and Coinductively [PDF]

open access: yesLogical Methods in Computer Science, 2017
Traditionally, formal languages are defined as sets of words. More recently, the alternative coalgebraic or coinductive representation as infinite tries, i.e., prefix trees branching over the alphabet, has been used to obtain compact and elegant proofs of classic results in language theory.

The Maximal Complexity of Quasiperiodic Infinite Words

open access: yesAxioms, 2021
A quasiperiod of a finite or infinite string is a word whose occurrences cover every part of the string. An infinite string is referred to as quasiperiodic if it has a quasiperiod.

On formal universals in phonology [PDF]

open access: yes, 2009
Understanding the universal aspects of human language structure requires comparison at multiple levels of analysis. While Evans & Levinson (E&L) focus mostly on substantive variation in language, equally revealing insights can come from studying formal ...

Factorization in Formal Languages [PDF]

open access: yes, 2015
We consider several novel aspects of unique factorization in formal languages. We reprove the familiar fact that the set uf(L) of words having unique factorization into elements of L is regular if L is regular, and from this deduce an quadratic upper and lower bound on the length of the shortest word not in uf(L).

Formalizing Homogeneous Language Embeddings [PDF]

open access: yesElectronic Notes in Theoretical Computer Science, 2010
The cost of implementing syntactically distinct Domain Specific Languages (DSLs) can be reduced by homogeneously embedding them in a host language in cooperation with its compiler. Current homogeneous embedding approaches either restrict the embedding of multiple DSLs in order to provide safety guarantees, or allow multiple DSLs to be embedded but ...

Language and language : Approaches to metaphor

open access: yesCorela, 2016
The work of Pierre-Yves Raccah is characterized by great precision and rigour; this is well illustrated by the terminological distinction he has established between natural language (such as French or English), and formal language as employed by ...

Formal Basis of a Language Universal

open access: yesComputational Linguistics, 2021
Steedman (2020) proposes as a formal universal of natural language grammar that grammatical permutations of the kind that have given rise to transformational rules are limited to a class known to mathematicians and computer scientists as the “separable ...
