- Darboux curves on surfaces I
この論文をさがす
抄録
<p>In 1872, G. Darboux defined a family of curves on surfaces of ℝ3 which are preserved by the action of the Möbius group and share many properties with geodesics. Here, we characterize these curves under the view point of Lorentz geometry and prove that they are geodesics in a 3-dimensional sub-variety of a quadric Λ4 contained in the 5-dimensional Lorentz space ℝ51 naturally associated to the surface. We construct a new conformal object: the Darboux plane-field 𝒟 and give a condition depending on the conformal principal curvatures of the surface which guarantees its integrability. We show that 𝒟 is integrable when the surface is a special canal.</p>
