              Abstract
              In this paper we give the representation formulas for spacelike curves in twodimensional lightlike cone mathbb Q2 and threedimensional lightlike cone mathbb Q3 Using these formulas we discuss the properties and structures of cone curves in mathbb Q2 and mathbb Q3 Some examples are also given
