The unit binormal
B is a Killing vector field on Frenet helices; hence, their evolution under the B-flow satisfies [x.sub.t] = B, so we assume k(s, t) is not constant.
Where t is the unit tangent vector, b is the unit binormal
vector and n is the unit binormal
vector; k is the curvature and [tau] is the torsion.
