The concept of relative N-compactness is defined and characterized in terms ofnets. It is shown that the relative N-compactness is hereditary with respect to L-fuzzy setsand the relative N-compactness is L-good extension. Some connections between the N-compactness and the relative N-compactness are investigated. It is also proved that inducedrelative N-compact spaces are productive, and the product of finite relative compact sets isrelative compact. 展开更多

In this paper, we prove that (L^X,5) is T0,T1, T2, regular (T3), normal (T4) and completely regular spaces if and only if (R(L)^X, ω(δ)) is T0, T1, T2, regular (T3), normal (T4) and completely regula... In this paper, we prove that (L^X,5) is T0,T1, T2, regular (T3), normal (T4) and completely regular spaces if and only if (R(L)^X, ω(δ)) is T0, T1, T2, regular (T3), normal (T4) and completely regular spaces, respectively, and (L^X,δ) is N-compact if and only if (R(L)^X, ω(δ)) is N-compact. 展开更多

It is no doubt that the researches on the N-compactness in[1] and [2] are a nice and important achievement in L-fuzzy topology. There is a natural and interesting question about the N-compactness——the sheaf structures of N-compact sets. It is proved that, for weakly induced Hausdorff space, the N-compactness of L-fuzzy set A in the upper 展开更多

In this paper we give a characteristic property of convergence of nets in induced I(L)-topological spaces and a simplified proof for the N-compactness being an I(L)-'good extension'.
