Abstract: The authors study the actions on spacelike curves with null principal normal vector in 3-dimensional Minkowski space.The Euler-Lagrange equation and two Killing vector fields are found.The authors integrate the Frenet equations by constructing cylindrical coordinates around the Killing field

Key words: spacelike curve, null principal normal, Killing field
