Abstract: In this paper we study projective and injective unars, as well as unars that satisfy conditions that are weakenings of the concepts of projectivity and injectivity. Namely, an algebraic description of projective, weakly-, quasi- and pseudo-projective, injective, weakly-, quasi- and pseudo-injective unars is given.
Key words: projective object, injective object, unar.
