Ehrenfeucht-fra¨ iss´e games on a class of Scattered linear orders
Abstract
Two structures A and B are n-equivalent if player II has a winning strategy in the n-move Ehrenfeucht-Fra¨ıss´e game on A and B. In earlier papers we studied n-equivalence classes of ordinals and coloured ordinals. In this paper we similarly treat a class of scattered order-types, focussing on monomials and sums of monomials in! And it’s reverse! _.
