Abstract

This article introduces a weak difference on a poset as a generalization of a difference on a poset and deals with connections between weak differences and weak BCK-algebras. In particular, conditions under which a poset with a certain weak difference is a meet semilattice are provided. These conditions are then applied to some partial orders on rings, namely the weak right star order and the strong right star order on a right-strong Rickart ring, as well as the sharp order on a certain subset of an arbitrary unitary ring.


The bilateral project between Slovenia and Latvia (Ordered structures in Rickart rings) was financially supported by the Slovenian Research and Innovation Agency, ARIS (Grant BI-LV/20-22-002). The second author acknowledges the financial support from the Slovenian Research and Innovation Agency ARIS (research program P1-0288).
