Title
Surjectivity of Functors on Grammars
Abstract
We present a procedure for deciding a sufficient condition for equivalence of context-free grammars. The main focus of the paper is on deciding whether a given functor between two grammars is surjective. An additional theorem gives us the means for deciding a certain type of structural similarity which is defined by the existence of such a functor.
