“…As a generalization of lattices Halaš [6] studied annihilators in ordered sets. This was followed by a lot of studies and research on the concept of annihilator in many algebraic structures and classes, for instance: almost distributive lattices [3],0-almost distributive lattices [4], distributive dual weakly complemented lattice [17], BCK-algebras [7], standard QBCC algebras [14], C-algebra [16], and many other classes.…”
