报告题目：Soju structures inBCK/BCI-algebras
报 告 人：Prof. Dr. Young Bae Jun
报告摘要：We introduce a new structure, so called asoju structure, by combining intuitionistic fuzzy set and soft set. We applythis structure to BCK/BCI-algebras, and introduce the notion of soju subalgebraand soju ideal in BCK/BCI-algebras. We investigate related properties, and definea strong soju subalgebra in BCI-algebras. We provide a condition for a sojusubalgebra to be strong. We consider the relation between soju subalgebra andsoju ideal. We provide conditions for a soju structure to be a soju ideal in aBCK-algebra. We discuss characterizations of soju subalgebra and soju ideal,and consider homomorphic image and preimage of soju subalgebra.
