论文摘要
如果多种代数为限制,则称为限制,但其所有适当的亚各个属性都是有限的。我们提出了一对新的单型限制,并表明,与杰克逊,张和卢的五个极限品种以及以前命名的作者一起发现的五个极限品种,J-Trivial Monoids恰好有七个极限品种。
A variety of algebras is called limit if it is non-finitely based but all its proper subvarieties are finitely based. We present a new pair of limit varieties of monoids and show that together with the five limit varieties of monoids previously discovered by Jackson, Zhang and Luo and the first-named author, there are exactly seven limit varieties of J-trivial monoids.
