Splitting conditions for classes of meet automata
Ondřej Klíma, Libor Polák · 2007
In a recent paper we introduced meet automata as a new (algebraic) concept for studying natural classes of languages. We factorized the most general Eilenberg-type theorem through varieties of meet automata. The only syntactic presentation of such classes was the usage of pseudoidentities on transformation semirings of such automata. Here we present a new type of conditions suitable for identification of classes of meet automata. We found rich hierarchies of such classes, several of them related to the reversible automata.
