Abstract: The concept of $\delta $-ideals is introduced in a pseudo-complemented distributive lattice and some properties of these ideals are studied. Stone lattices are characterized in terms of $\delta $-ideals. A set of equivalent conditions is obtained to characterize a Boolean algebra in terms of $\delta $-ideals. Finally, some properties of $\delta $-ideals are studied with respect to homomorphisms and filter congruences.
