Syntactic Minimization of Nondeterministic Finite Automata

Robert Samuel Ralph Myers, Henning Urbat

Nondeterministic automata may be viewed as succinct programs implementing deterministic automata, i.e. complete specifications. Converting a given deterministic automaton into a sm…

Nondeterministic Syntactic Complexity

Robert Myers, Stefan Milius, Henning Urbat

We introduce a new measure on regular languages: their nondeterministic syntactic complexity. It is the least degree of any extension of the `canonical boolean representation' of t…

Representing Semilattices as Relations

Robert Samuel Ralph Myers

We represent finite join-semilattices and join-preserving morphisms as a category whose objects and morphisms are binary relations. It is a quotient category of 's…

Nondeterministic Automata and JSL-dfas

Robert Samuel Ralph Myers

We introduce the category of dependency automata. A dependency automaton consists of two nondeterministic finite automata, with a relation between their states satisfying condition…

Varieties of Languages in a Category

Jiri Adamek, Stefan Milius, Robert Myers +1

Eilenberg's variety theorem, a centerpiece of algebraic automata theory, establishes a bijective correspondence between varieties of languages and pseudovarieties of monoids. In th…

Generalized Eilenberg Theorem I: Local Varieties of Languages

Jiri Adamek, Stefan Milius, Robert Myers +1

We investigate the duality between algebraic and coalgebraic recognition of languages to derive a generalization of the local version of Eilenberg's theorem. This theorem states th…
