单关系幺半群的字问题综述

The Word Problem for One-relation Monoids: A Survey

Carl-Fredrik Nyberg-Brodda

摘要:

本调查的目的是提供一个概述的最古老的和最著名的组合代数开放问题之一:字问题的一个关系幺半群。我们提供了一个历史的问题开始于1914年,并给出了详细的概述证明的中央结果,特别是那些由于Adian和他的学生Oganesian。在展示了如何将问题简化为左可消的情况之后,调查的后半部分集中在解决这个家庭中部分情况的各种方法上。我们完成了一些现代和最近的结果有关这个问题,包括一个链接到Collatz猜想。在此过程中,我们强调并解决了多年来文献中出现的一些不正确和不准确的陈述。我们还填补了一个定理连接特殊的逆幺半群的一个关系幺半群证明的空白,并稍微加强了这个定理的陈述。

英文摘要:

This survey is intended to provide an overview of one of the oldest and most celebrated open problems in combinatorial algebra: the word problem for one-relation monoids. We provide a history of the problem starting in 1914, and give a detailed overview of the proofs of central results, especially those due to Adian and his student Oganesian. After showing how to reduce the problem to the left cancellative case, the second half of the survey focuses on various methods for solving partial cases in this family. We finish with some modern and very recent results pertaining to this problem, including a link to the Collatz conjecture. Along the way, we emphasise and address a number of incorrect and inaccurate statements that have appeared in the literature over the years. We also fill a gap in the proof of a theorem linking special inverse monoids to one-relation monoids, and slightly strengthen the statement of this theorem.
