In class you defined the Darboux transformation \(\eta\colon \mathbb R\to \mathbb R^3\) of a smooth space curve \(\gamma\colon \mathbb R\to \mathbb R^3\). By construction, the distance between corresponding points is constant. Or phrased differently, there is \(S\colon \mathbb R \to … Continue reading Tutorial 4 – Darboux transformations
