On Fuzzy Separation Axioms Using Fuzzy Regularly Open Sets
Park, Kuo-Duok,Soung, Goang-Ou,Im, Young-Bin 동국대학교 자연과학연구소 1992 자연과학연구 논문집 Vol.12 No.-
본 논문은 퍼지 정칙 개집합을 소개하여 퍼지 거의 연속사상과 퍼지 거의 개사상의 성질들을 알아본다. 그리고 퍼지 개집합 대신 퍼지 정칙 개집합으로 정의한 새로운 유형의 퍼지 분리 공리를 연구한다. This paper is devoted to the study of the role of fuzzy regularly open sets. We prove some properties of fuzzy almost continuous mappings and introduce fuzzy almost open mappings. Further we discuss a fuzzy almost separation axioms, by using the concept of fuzzy regularly open sets in place of fuzzy open sets.
Fuzzy Almost Continuous Mappings and Fuzzy Almost Quasi-Compact Mappings
Park, Kuo-Duok,Im, Young-Bin,Soung, Goang-Ou Korean Institute of Intelligent Systems 1995 한국지능시스템학회논문지 Vol.5 No.1
In this paper we introduce the class of fuzzy almost contrinuous mappings. It contains the class of fuzzy continuous mappings and is contained in the class of fuzzy weakly continuous mappings. In section 3 we discuss various properties of such mappings. In section 4 we also introduce the notion of fuzzy almost quasi-compact mappings and give relations between fuzzy almost quasi-compact mappings and the mapping which are introduced in section 2 and 3.
