Further, we give necessary and sufficient conditions for unit speed space curves to have 1-type Darboux vectors. Moreover, we obtain some characterizations of helices according to Darboux vector.eninfo:eu-repo/semantics/closedAccessScience & technologyPhysical sciencesMathematicsArticle00040123890001537938831210.4134/CKMS.2016.31.2.379
