Abstract

We show that the inclusion problem is decidable for rational languagesof words indexed by scattered countable linear orderings. The method leans on a reduction tothe decidability of the monadic second order theory of the infinite binary tree [9].

Keywords

Finite automatawords over linear orderings-treesmonadic second order logics.
