Fuzzy lattices are the basic objects which L-fuzzy topology bases on.
We study relations of fuzzy lattices and symmetric complete lattices f
rom category points of view. A relevant fuzzy lattice omega(L) and a r
elevant symmetric complete Heyting algebra phi(L) are constructed from
a given symmetric complete lattice L. We prove that the constructions
omega and phi are two functors and they have reflective properties ov
er relevant categories.
