Small Conjunctive Varieties of Regular Languages

نویسنده

  • Libor Polák
چکیده

The author’s modification of Eilenberg theorem relates the so-called conjunctive varieties of regular languages with pseudovarieties of idempotent semirings. Recent results by Pastijn and his co-authors lead to the description of the lattice of all (pseudo)varieties of idempotent semirings with idempotent multiplication. We describe here the corresponding 78 varieties of languages.

On varieties of meet automata

Eilenberg’s variety theorem gives a bijective correspondence between varieties of languages and varieties of finite semigroups. The second author gave a similar relation between conjunctive varieties of languages and varieties of semiring homomorphisms. In this paper, we add a third component to this result by considering varieties of meet automata. We consider three significant classes of lang...

Conjunctive Context-Free Path Queries

In graph query languages, regular expressions are commonly used to specify the labeling of paths. A natural step in increasing the expressive power of these query languages is replacing regular expressions by context-free grammars. With the Conjunctive Context-Free Path Queries (CCFPQ) we introduce such a language based on the well-known Conjunctive Regular Path Queries (CRPQ). First, we show t...

Varieties of Unranked Tree Languages

We study varieties that contain unranked tree languages over all alphabets. Trees are labeled with symbols from two alphabets, an unranked operator alphabet and an alphabet used for leaves only. Syntactic algebras of unranked tree languages are defined similarly as for ranked tree languages, and an unranked tree language is shown to be recognizable iff its syntactic algebra is regular, i.e., a ...

Conjunctive Grammars Can Generate Non-regular Unary Languages

Conjunctive grammars were introduced by A. Okhotin in [1] as a natural extension of context-free grammars with an additional operation of intersection in the body of any production of the grammar. Several theorems and algorithms for context-free grammars generalize to the conjunctive case. Still some questions remained open. A. Okhotin posed nine problems concerning those grammars. One of them ...

Regular tree languages and quasi orders

Regular languages were characterized as sets closed with respect to monotone well-quasi orders. A similar result is proved here for tree languages. Moreover, families of quasi orders that correspond to positive varieties of tree languages and varieties of finite ordered algebras are characterized.
