Relationships among quasivarieties induced by the min networks on inverse semigroups
Ying-Ying Feng, Li-Min Wang, Zhi-Yong Zhou
A congruence on an inverse semigroup is determined uniquely by its kernel and trace. Denoting by and the least congruence on having the same kernel and the same…
A new approach to a network of congruences on an inverse semigroup
Ying-Ying Feng, Li-Min Wang, Lu Zhang +1
This paper enriches the list of known properties of congruence sequences starting from the universal relation and successively performing the operators lower and lower . Two…
Some special congruences on completely regular semigroups
Li-Min Wang, Ying-Ying Feng, Hong-Hua Chen
This paper enriches the list of properties of the congruence sequences starting from the universal relation and successively performing the operations of lower and lower . T…
Presentations for singular wreath products
Ying-Ying Feng, Asawer Al-Aadhami, Igor Dolinka +2
For a monoid and a subsemigroup of the full transformation semigroup , the wreath product is defined to be the semidirect product , with the coo…
