Parikh Matrices, Amiability and Istrail Morphism

Using the fact that the Parikh matrix mapping is not an injective mapping, the paper investigates some properties of the set of words having the same Parikh matrix; these words are called “amiable” or “M equivalent”. The presented paper uses the results obtained in [3] for the binary case. The aim is to distinguish the amiable words by using a morphism that provides additional information about...

Injectivity of the Parikh Matrix Mappings Revisited

We deal with the notion of M-unambiguity [5] in connection with the Parikh matrix mapping introduced by Mateescu and others in [7]. M-unambiguity is studied both in terms of words and matrices and several sufficient criteria for M-unambiguity are provided in both cases, nontrivially generalizing the criteria based on the γ-property introduced by Salomaa in [15]. Also, the notion of M-unambiguit...

Codifiable Languages and the Parikh Matrix Mapping

We introduce a couple of families of codifiable languages and investigate properties of these families as well as interrelationships between different families. Also we develop an algorithm based on the Earley algorithm to compute the values of the inverse of the Parikh matrix mapping over a codifiable context-free language. Finally, an attributed grammar that computes the values of the Parikh ...
