Projective and Injective Weak Distributive Lattice

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.
