Figure 5. Temporal evolutions of curvature $\kappa \left(\xi ,t\right)$ (a) and torsion $\tau \left(\xi ,t\right)$ (c) corresponding to a super-regular breather, see equation (C2) in appendix C. (b) and (d) are variations of $\kappa \left(\xi ,t\right)$ and $\tau \left(\xi ,t\right)$ at different times. Other parameters are κ0 = 1, τ0 = 0.05, R = 1.1 and φ = π/8.
