Several types of one-sided partial orders in rings
No full textIn this paper, we investigate one-sided sharp partial orders and one-sided core and dual core partial orders in rings. Moreover, their characterizations and relations with other partial orders are given.This research is supported by the National Natural Science Foundation of China (No. 11801124), the Natural Science Foundation of Anhui Province (No. 1808085QA16), the Fundamental Research Funds for the Central Universities (No. JZ2018HGTB0233) and the Portuguese Funds through FCT- ‘Fundação para a
