We show that the inclusion problem is decidable for rational languages of words indexed by scattered countable linear orderings. The method leans on a reduction to the decidability of the monadic second order theory of the infinite binary tree .
Mathematics Subject Classification: 68Q45 / 03D05.
Key words: Finite automata / words over linear orderings-trees / monadic second order logics.
