This paper is devoted to the study of H1 topological molecular lattices, a generalization of the Hausdor fuzzy topological spaces. Some primary properties of such topological molecular lattices are discussed. For any complete and completely distributive lattice L, the existence and uniqueness of minimal H1 co-topologies on L are investigated, and the characteristic theorem of minimal H1 co-topologies on L is established.

For L a closed sets lattice, we prove the existence and a characterization theorem of the minimal elements of T 3LX, where T 3

This paper is a sequel to Li (1999). For some classes F of L-valued Zadeh functions, we will discuss two problems connected with inverse limits in LTop, K1HLTop and K2HLTop: (1) Will the condition that all L-valued Zadeh functions between factor L-fts of two given inverse systems are in F imply that the induced limit LTop-morphism is in F? (2) Will the condition that all bonding L-valued Zadeh functions are in F imply that all projective L-valued Zadeh functions are in F?

This paper studies local strong F1 connectedness and local Q-connectedness of L-topological spaces. It is shown that every L-interval J (L) and its weak induci.cation J(L) are both local strong F1 connected andlocal Q-connected, and that the local Q-connectedness of an L-topological space is equivalent to that of its induced I (L)-topological space.

Based on the consideration to the layer structures of fuzzy lattices and the level topologies of L-fuzzy topological spaces, a connectedness is dened for an arbitrary L-fuzzy set in this paper. This denition reects the degree of connectivity of an L-fuzzy set. It is shown that the connectedness of L-fuzzy topological spaces is an L-good extension, multiplicative and preserved under continuous L-valued Zadeh functions, and that the inverse limit of continuums is a continuum. General L-fuzzy intervals and H-intervals are dened and connectedness of them are proved. It is also shown that the connectedness of an L-fuzzy topological space is equivalent to the connectedness of its induced I (L)-fuzzy topological space.
