论文摘要
我们通常考虑两个块替换及其固定点。我们证明其中一些具有简单的结构：它们的固定点是形态序列。其他人本质上更为复杂，例如Kolakoski序列。我们证明了基础3/2中的thue-morse序列。
We consider in general two-block substitutions and their fixed points. We prove that some of them have a simple structure: their fixed points are morphic sequences. Others are intrinsically more complex, such as the Kolakoski sequence. We prove this for the Thue-Morse sequence in base 3/2.
