    • Complex Fuzzy Sets with Application in BCK/BCI-Algebras 

      Jun, Young Bae; Xin, Xiao Long (Wydawnictwo Uniwersytetu Łódzkiego, 2019-10-30)
      As a generation of fuzzy set, the notion of complex fuzzy set which is an innovative concept is introduced by Ramot, Milo, Friedman and Kandel. The purpose of this article is to apply complex fuzzy set to BCK/BCI-algebras. ...
    • On the Category of EQ-algebras 

      Akhlaghinia, Narges; Aaly Kologani, Mona; Borzooei, Rajab Ali; Xin, Xiao Long (Wydawnictwo Uniwersytetu Łódzkiego, 2021-01-20)
      In this paper, we studied the category of EQ-algebras and showed that it is complete, but it is not cocomplete, in general. We proved that multiplicatively relative EQ-algebras have coequlizers and we calculated coproduct ...
    • Positive Implicative Soju Ideals in BCK-Algebras 

      Xin, Xiao Long; Borzooei, Rajab Ali; Jun, Young Bae (Wydawnictwo Uniwersytetu Łódzkiego, 2019)
      The notion of positive implicative soju ideal in BCK-algebra is introduced, and several properties are investigated. Relations between soju ideal and positive implicative soju ideal are considered, and characterizations ...
