TY - JOUR ID - 491139 AU - Kunc, Michal PY - 2003 TI - Equational description of pseudovarieties of homomorphisms JF - RAIRO - Theoretical Informatics and Applications VL - 37 IS - 3 SP - 243 EP - 243 PB - EDP Sciences SN - 09883754 KW - Pseudovariety KW - Pseudoidentity KW - Implicit operation KW - Variety of regular languages KW - Syntactic homomorphism UR - http://www.edpsciences.org/articles/ita/abs/2003/03/ita0311/ita0311.html N2 - The notion of pseudovarieties of homomorphisms onto finite monoids was recently introduced by Straubing as an algebraic characterization for certain classes of regular languages. In this paper we provide a mechanism of equational description of these pseudovarieties based on an appropriate generalization of the notion of implicit operations. We show that the resulting metric monoids of implicit operations coincide with the standard ones, the only difference being the actual interpretation of pseudoidentities. As an example, an equational characterization of the pseudovariety corresponding to the class of regular languages in AC0 is given. ER -
