报告题目：Soju structures in BCK/BCI-algebras

报 告 人：Prof. Dr. Young Bae Jun

报告时间：2018年6月28日（星期四）15:45—16:30

报告地点：理学院418室

报告摘要：We introduce a new structure, socalled a soju structure, by combining intuitionistic fuzzy set and soft set. Weapply this structure to BCK/BCI-algebras, and introduce the notion of sojusubalgebra and soju ideal in BCK/BCI-algebras. We investigate relatedproperties, and define a strong soju subalgebra in BCI-algebras. We provide acondition for a soju subalgebra to be strong. We consider the relation betweensoju subalgebra and soju ideal. We provide conditions for a soju structure tobe a soju ideal in a BCK-algebra. We discuss characterizations of sojusubalgebra and soju ideal, and consider homomorphic image and preimage of sojusubalgebra.
