On s-weakly gw-closed sets in w-spaces
Autor: Won Keun Min
Publikováno v: Journal of King Saud University: Science, Vol 30, Iss 4, Pp 479-482 (2018)
The purpose of this note is to introduce the notion of s-weakly gw-closed set in w-spaces and to study its some basic properties. In particular, the relationships among wg-closed sets, w-semi-closed sets and s-weakly g-closed sets are investigated. K

Attribute Reduction in Soft Contexts Based on Soft Sets and Its Application to Formal Contexts
Autor: Won Keun Min
Publikováno v: Mathematics, Vol 8, Iss 5, p 689 (2020)
We introduce the notion of the reduct of soft contexts, which is a special notion of a consistent set for soft contexts. Then, we study its properties and show that this notion is well explained by the two classes, 1 0 and 2 0 , of independent attrib

Consistent Sets of Soft Contexts Defined by Soft Sets
Autor: Won Keun Min
Publikováno v: Mathematics, Vol 7, Iss 1, p 71 (2019)
We introduce the notion of consistent sets of soft contexts and investigate its characterizations. For the purpose of studying the characterizations of consistent sets, we introduce the notions of 1 0 and 2 0 classes of independent attributes. By stu

Neighborhood spaces
Autor: D. C. Kent, Won Keun Min
Publikováno v: International Journal of Mathematics and Mathematical Sciences, Vol 32, Iss 7, Pp 387-399 (2002)
Neighborhood spaces, pretopological spaces, and closure spaces are topological space generalizations which can be characterized by means of their associated interior (or closure) operators. The category NBD of neighborhood spaces and continuous maps

γ-sets and γ-continuous functions
Autor: Won Keun Min
Publikováno v: International Journal of Mathematics and Mathematical Sciences, Vol 31, Iss 3, Pp 177-181 (2002)
We introduce a new class of sets, called γ-sets, and the notion of γ-continuity and investigate some properties and characterizations. In particular, γ-sets and γ-continuity are used to extend known results for semi-open sets and semi-continuity.

Soft concept lattice for formal concept analysis based on soft sets: theoretical foundations and applications
Autor: Won Keun Min, Young Key Kim
Publikováno v: Soft Computing. 23:9657-9668
Formal concept analysis (FCA) is an important theory on the study of hierarchical structures caused by a binary relation between objects and attributes. And it is well known that a soft set always induces a binary relationship between objects and att
