Department of Mathematics, Northeastern University, 110004 Shenyang P. R. China, e-mail:,

Abstract: In this paper, we study curves in the lightlike cone. We first obtain the conformally invariant arc length in the $(n+1)$-dimensional lightlike cone and then characterize some curves in the 2-dimensional lightlike cone and 3-dimensional lightlike cone.

Keywords: lightlike cone, conformal invariant, Frenet formula, curvature function

Classification (MSC2000): 53A04, 53A30, 53B30
