Congruences on ample semigroups
A El-Qallali - Semigroup Forum, 2019 - Springer
Congruences on an ample semigroup S are investigated. For any admissible congruence ρ
ρ on S, the minimum σ _ ρ σ ρ (the maximum μ _ ρ μ ρ) admissible congruence on S whose …

Abundant semigroups with Q-adequate transversals and some of their special cases
X Guo, KP Shum - Algebra Colloquium, 2007 - World Scientific
Regular semigroups with multiplicative inverse transversals were first studied by Blyth and
McFadden in 1982. In this paper, we extend the concept of inverse transversals to some kind …

Pretzel monoids
D Heath, M Kambites, N Szakács - arXiv preprint arXiv:2405.00589, 2024 - arxiv.org
We introduce an interesting class of left adequate monoids which we call pretzel monoids.
These, on the one hand, are monoids of birooted graphs with respect to a naturalglue-and …
