RS-Compactness in L-fuzzy Topological Spaces
M. E. EL-Shafei,I. M. Hanafy,A. I. Aggour 경북대학교 자연과학대학 수학과 2002 Kyungpook mathematical journal Vol.42 No.2
The concept of RS-compactness is introduced and studied in L-fts's. We give some characterizations of RS-compactness in terms of regular closed, semiopen and β-open L-fuzzy sets. We also characterize RS-compactness in the sense of convergent prefilterbasis and by means of finite intersection property. We investigate the image and the inverse image of RS-compact spaces under some types of functions.
