This paper is devoted to the study of the inverse limits in LTop, the category of L-fuzzy topological spaces and continuous L-valued Zadeh-functions between them, where L is a completely distributive complete lattice. Structures of such limits are described and a series of their properties are investigated. Furthermore, the mappings between two arbitrary inverse systems is de ned and some of their properties are discussed for the case of category LTop.

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.

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.

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