The purpose of this project is to discuss the concept of"Properties of Stone Almost Distributive lattice" in terms of its dense element and its center. we define different set of axioms which characterize the class of"Proper1ies of Stone Almost Distributive Lattice" and proved that, this axioms independent, in addition to this, we gave a few more necessary and sufficient condition for ADL to be a Stone ADL in terms of principal ideals generated by the semi-complement of an element of a lattice.

A Project Submitted in Partial of the Requirements for the Degree of Master of Science in Mathenlatics.
