关于有限完全重写系统与大子半群

On finite complete rewriting systems and large subsemigroups

K. B. Wong, P. C. Wong

摘要:

设$S$是一个半群,$T$是$S$中指数有限的子半群(即集合$S\setminus T$是有限的).子半群$T$也称为$S$的大子半群。众所周知,如果$T$有一个有限的完全重写系统,那么$S$也有。在本文中,我们将证明相反的,即如果$S$有一个有限的完全重写系统,那么$T$。我们的证明是纯粹的组合,也是建设性的。

英文摘要:

Let $S$ be a semigroup and $T$ be a subsemigroup of finite index in $S$ (that is, the set $S\setminus T$ is finite). The subsemigroup $T$ is also called a large subsemigroup of $S$. It is well known that if $T$ has a finite complete rewriting system then so does $S$. In this paper, we will prove the converse, that is, if $S$ has a finite complete rewriting system then so does $T$. Our proof is purely combinatorial and also constructive.
