论文摘要
我们在集合$ \ {0,1,2,3 \} $中研究Centryser克隆的一元部分，所谓的集中单层。我们描述并计数所有集中式单体中的所有集中式单体$ \ {0,1,2,3 \} $具有多数操作作为证人，我们列出了完整转换的最大适当下变换的适当适当的下monoid。这扩展了Goldstern，Machida和Rosenberg的先前工作。
We study unary parts of centraliser clones on the set $\{0,1,2,3\}$, so-called centralising monoids. We describe and count all centralising monoids on the set $\{0,1,2,3\}$ having majority operations as witnesses, and we list the inclusion maximal proper submonoids of the full transformation monoid among them. This extends previous work by Goldstern, Machida and Rosenberg.
