Some kinds of (∈,∈∨q)-interval-valued fuzzy ideals of BCI-algebras

GENERAL TYPES OF(∈,∈∨qk)-FUZZY SUBSEMIGROUPS IN SEMIGROUPS

“…This was further studied in detail by Bhakat [1,2], Bhakat and Das [3,4], and Yuan et al [28]. This notion is applied to semigroups and groups (see [2], [3], [4], [12], [26], [27]), BCK/BCI-algebras (see [6], [8], [9], [10], [22], [30], [31]), and (pseudo-) BL-algebras (see [21],…”

Applications of Soft Sets in BE-Algebras

“…It is known that the class of BCK-algebras is a proper subclass of the class of BCI-algebras. Ma et al studied (∈, ∈ ∨ )-tyle (interval-valued) fuzzy ideals in BCI-algebras and soft 0 -algebras (see [3][4][5]). As a generalization of a BCK-algebra, H. S. Kim and Y. H. Kim [6] introduced the notion of a BEalgebra and investigated several properties.…”

Some characterizations of (¯∈γ, ¯∈γ v<em> ¯q</em>δ)-fuzzy fantastic ideals in BCH-algebras

“…Davvaz and Corsini (2007) redefined fuzzy H v -submodule and many-valued implications. In Ma et al (2008Ma et al ( , 2009 discussed some kinds of (∈ , q ∨ ∈ )-interval-valued fuzzy ideals of BCI-algebras. In Ma et al (2012) studied new types of fuzzy ideals of BCI-algebras.…”
