Kleene Theorem for Higher-Dimensional Automata

U Fahrenberg, C Johansen, G Struth… - Logical Methods in …, 2024 - lmcs.episciences.org
We prove a Kleene theorem for higher-dimensional automata. It states that the languages
they recognise are precisely the rational subsumption-closed sets of finite interval pomsets …

Myhill-Nerode Theorem for Higher-Dimensional Automata

U Fahrenberg, K Ziemiański - Fundamenta Informaticae, 2024 - fi.episciences.org
We establish a Myhill-Nerode type theorem for higher-dimensional automata (HDAs), stating
that a language is regular if and only if it has finite prefix quotient. HDAs extend standard …

Logic and languages of higher-dimensional automata

A Amrane, H Bazille, U Fahrenberg, M Fortin - International Conference on …, 2024 - Springer
In this paper we study finite higher-dimensional automata (HDAs) from the logical point of
view. Languages of HDAs are sets of finite bounded-width interval pomsets with interfaces …

Closure and decision properties for higher-dimensional automata

A Amrane, H Bazille, U Fahrenberg… - … Colloquium on Theoretical …, 2023 - Springer
In this paper we develop the language theory of higher-dimensional automata (HDAs).
Regular languages of HDAs are sets of finite interval partially ordered multisets (pomsets) …

Regular monoidal languages

M Earnshaw, P Sobociński - arxiv preprint arxiv:2207.00526, 2022 - arxiv.org
We introduce regular languages of morphisms in free monoidal categories, with their
associated grammars and automata. These subsume the classical theory of regular …

Posets with interfaces as a model for concurrency

U Fahrenberg, C Johansen, G Struth… - Information and …, 2022 - Elsevier
We introduce posets with interfaces (iposets) and generalise their standard serial
composition to a new gluing composition. In the partial order semantics of concurrency …

[PDF][PDF] Higher-dimensional timed and hybrid automata

U Fahrenberg - Leibniz Transactions on Embedded Systems, 2022 - ojs.dagstuhl.de
We introduce a new formalism of higher-dimensional timed automata, based on Pratt and
van Glabbeek's higher-dimensional automata and Alur and Dill's timed automata. We prove …

Regular planar monoidal languages

M Earnshaw, P Sobociński - Journal of Logical and Algebraic Methods in …, 2024 - Elsevier
We introduce regular languages of morphisms in free monoidal categories, with their
associated grammars and automata. These subsume the classical theory of regular …

Presenting interval pomsets with interfaces

A Amrane, H Bazille, E Clement, U Fahrenberg… - … on Relational and …, 2024 - Springer
Interval-order partially ordered multisets with interfaces (ipomsets) have shown to be a
versatile model for executions of concurrent systems in which both precedence and …

Languages of higher-dimensional timed automata

A Amrane, H Bazille, E Clement… - … on Applications and …, 2024 - Springer
We present a new language semantics for real-time concurrency. Its operational models are
higher-dimensional timed automata (HDTAs), a generalization of both higher-dimensional …
