ABSTRAK

 

Sifat warisan dan kepadatan kabur dalam ruang Hausdorff kabur dikaji. Beberapa pencirian ruang Hausdorff kabur diberikan. Selanjutnya ditakrifkan tertutup mutlak kabur dan ruang minimum Hausdorff kabur serta perkaitannya dikaji. Penciriannya melalui turas kabur dan tudung kabur diberikan.

 

ABSTRACT

 

Some hereditary and fuzzy compactness properties in fuzzy Hausdorff spaces are studied. Some characterizations of the fuzzy Hausdorff spaces are given. Furthermore we define the fuzzy absolutely closed and fuzzy Hausdorff minimal space and study its relationships. Its characterizations via fuzzy filters and fuzzy covering are given.
