Two structures A and B are n-equivalent if Player II has a winning strategy in the n-move Ehrenfeucht-Fraïssé game on A and B. In earlier articles we studied n-equivalence classes of ordinals and coloured ordinals. In this article we similarly treat a class of scattered order-types, focussing on monomials and sums of monomials in ω and its reverse ω*.

EHRENFEUCHT-FRAÏSSÉ 对一类分散线性顺序的博弈

两种结构一种和乙是n- 如果玩家 II 在n- 移动 Ehrenfeucht-Fraïssé 游戏一种和乙. 在之前的文章中，我们研究过n-序数和有色序数的等价类。在本文中，我们同样处理了一类分散阶类型，重点关注单项式和单项式之和ω及其相反ω*。
