[논문]Foldness of Bipolar Fuzzy Sets and Its Application in BCK/BCI-Algebras
Young Bae Jun, Seok-Zun Song
Recent trends in modern information processing have focused on polarizing information,
and and bipolar fuzzy sets can be useful. Bipolar fuzzy sets are one of the important tools that can be
used to distinguish between positive information and negative information. Positive information, for
example, already observed or experienced, indicates what is guaranteed to be possible, and negative
information indicates that it is impossible, prohibited, or certainly false. The purpose of this paper is
to apply the bipolar fuzzy set to BCK/BCI-algebras. The notion of (translated) k-fold bipolar fuzzy
sets is introduced, and its application in BCK/BCI-algebras is discussed. The concepts of k-fold bipolar
fuzzy subalgebra and k-fold bipolar fuzzy ideal are introduced, and related properties are investigated.
Characterizations of k-fold bipolar fuzzy subalgebra/ideal are considered, and relations between k-fold
bipolar fuzzy subalgebra and k-fold bipolar fuzzy ideal are displayed. Extension of k-fold bipolar fuzzy
subalgebra is discussed.
