Abstract: This paper investigates H-fuzzy ideals of distributive join-semilattices with least element 0 whose codomain is a complete lattice that satisfies the infinite meet distributive law. We also construct a number of characterizations for any H-fuzzy ideal generated by an H-fuzzy subset. It is also proved that the class of all H-fuzzy ideals of any distributive join-semilattice with 0 is a complete lattice and forms an algebraic closure H-fuzzy set system. We also introduce the concept of H-valued weights over a distributive join-semilattice with 0, and we derive a lattice isomorphism between the class of all H-fuzzy ideals of any distributive join-semilattice with 0 and the lattice of all H-valued weights over it. The concept of H-fuzzy filters of distributive join-semilattices with 0 is presented, and it is characterized using level sets.
