Certain equivalence relations on epigroups

Jingguo Liu


In this paper certain equivalences on an epigroup are introduced and the congruences generated by these equivalences are investigated. In addition, the join between Green's relations $\cal H$ (or $\cal D$) and anyone  of these given equivalences  is considered and the sublattices generated by them are depicted.
