Projective and Injective Weak Distributive Lattice

Abstract

This Paper is Concerned with solving problems existence with  quasi projective and quasi injective objects and retracts respectively over problems with projective and injective objects and retracts  in the category whose objects are the complete quasi lattice and morphism are the complete quasi lattice homomorphism from the point of view .in this paper we mentioned here some necessary and sufficient  conditions for the given lattice be quasi projective and quasi injective  and retracts respect.
