Figure 2From: Tangent-point energies and ropelength as Gamma-limits of discrete tangent-point energies on biarc curvesThe set \(\Sigma _{++}\) (boldface) contained in \(\Sigma _{+}\): Left: not cocircular and \(t_{0}\neq t_{1}\). Right: \(t_{0} = t_{1}\) and \(\langle t_{0}, e \rangle \neq 0\)Back to article page
