Limit varieties generated by finite non-J-trivial aperiodic monoids
Olga B. Sapir
Jackson and Lee proved that certain six-element monoid generates a hereditarily finitely based variety whose lattice of subvarieties contains an infinite ascending ch…

Classification of limit varieties of J-trivial monoids
S. V. Gusev, O. B. Sapir
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 t…

Limit varieties of -trivial monoids
Olga B. Sapir
We show that limit varieties of monoids recently discovered by Gusev, Zhang and Luo and their subvarieties are generated by monoids of the form for certain congruences …
