On k-radicals of Green's relations in semirings with a semilattice additive reduct
Tapas Kumar Mondal, Anjan Kumar Bhuniya (2013)
Discussiones Mathematicae - General Algebra and Applications
Similarity:
We introduce the k-radicals of Green's relations in semirings with a semilattice additive reduct, introduce the notion of left k-regular (right k-regular) semirings and characterize these semirings by k-radicals of Green's relations. We also characterize the semirings which are distributive lattices of left k-simple subsemirings by k-radicals of Green's relations.

Lattices and semilattices having an antitone involution in every upper interval
Ivan Chajda (2003)
Commentationes Mathematicae Universitatis Carolinae
Similarity:
We study -semilattices and lattices with the greatest element 1 where every interval [p,1] is a lattice with an antitone involution. We characterize these semilattices by means of an induced binary operation, the so called sectionally antitone involution. This characterization is done by means of identities, thus the classes of these semilattices or lattices form varieties. The congruence properties of these varieties are investigated.
