Rough Set Theory Applied to BCC-Algebras
نویسندگان
چکیده
In 1982, Pawlak introduced the concept of a rough set (see [6]). This concept is fundamental for the examination of granularity in knowledge. It is a concept which has many applications in data analysis (see [7]). Rough set theory is applied to semigroups and groups (see [4, 5]), and BCK-algebras (see [3]). In this paper, we apply the rough set theory to BCC-algebras, and we discuss the notion of upper/lower rough subalgebras/ideals which is an extended notion of a subalgebra/ideal in a BCC-algebra.

Rough subalgebras of some binary algebras connected with logics
In 1982, Pawlak introduced the concept of a rough set (see [10]). This concept is fundamental for the examination of granularity in knowledge. It is a concept which has many applications in data analysis (see [11]). Rough set theory is applied to semigroups and groups (see [7, 8]). In this paper, we apply the rough set theory to BCH-algebras, that is, to algebras of type (2,0) satisfying some s...
متن کاملFuzzy Derivations BCC-Ideals on BCC-Algebras
In the theory of rings, the properties of derivations are important. In [15], Jun and Xin applied the notion of derivations in ring and near-ring theory to BCI-algebras, and they also introduced a new concept called a regular derivation in BCI-algebras. They investigated some properties of its .In this manuscript, the concept of fuzzy left (right) derivations BCCideals in BCC-algebras is introd...
متن کاملOn hyper BCC-algebras
The study of BCK-algebras was initiated by Iséki [7] as a generalization of the concept of set-theoretic difference and propositional calculus. Iséki posed an interesting problem; whether the class of BCK-algebras is a variety. In connection with this problem Komori introduced in [9] a notion of BCC-algebra which is a generalization of a BCK-algebra and proved that the class of all BCC-algebras...
متن کاملRough Filters in BL-Algebras
We apply the rough set theory to BL-algebras. As a generalization of filters subalgebras of BL-algebras, we introduce the notion of rough filters subalgebras of BL-algebras and investigate some of their properties.
متن کاملA New Approach for Knowledge Based Systems Reduction using Rough Sets Theory (RESEARCH NOTE)
Problem of knowledge analysis for decision support system is the most difficult task of information systems. This paper presents a new approach based on notions of mathematical theory of Rough Sets to solve this problem. Using these concepts a systematic approach has been developed to reduce the size of decision database and extract reduced rules set from vague and uncertain data. The method ha...
