Combinatorial properties of texts

Andrzej Ehrenfeucht; P. ten Pas; Grzegorz Rozenberg

Un texte est considere comme un procede de loi. Les proprietes combinatoires de tels procedes de loi sont etudies. On donne en particulier des caracterisations combinatoires de textes alternants. On introduit egalement une sur-classe naturelle des textes alternants (appeles les textes sans saut) et on les caracterise tant par des proprietes combinatoires que par des proprietes de cloture
