The previous results seem to be incomplete. By using Contraction Mapping Theorem, we establish conditions under which solutions exist and are unique and have certain asymptotic properties.Englishnabla fractional difference equation; contraction mapping theorem; existence and uniqueness; asymptotic propertyArticle
