Monoids described by pushdown automata,a deterministic pushdown automaton. We prove that this family contains rational monoids, free groups and is closed under finitely generated submonoids and free products. We also consider other families of monoids of the same complexity than (PR)-monoids.

La complessità del farmaco naturaleUsing a recent result of G.Asser, an extention of Ackermann-Peter hierarchy of unary primitive recursive functions to string-functions is obtained. The resulting hierarchy classifies the string-functions according to their lexicographical growth.
