Abstract
Valence grammars were introduced by Gh. Păun in [8] as a grammatical model of chemical processes. Here, we focus on discussing a simpler variant which we call valuated grammars.We give some algebraic characterizations of the corresponding language classes. Similarly,we obtain an algebraic characterization of the linear languages. We also give some Nivat-like representations of valence transductions.
